... Other literature sources also concentrate on searching for and evaluating UX output heuristics. Authors in [15] state that "… in this article, we propose a novel AUX (Anticipated User eXperience) and UX evaluation method through which developers can obtain a knowledge base to create their designs… Intended Use: This criterion refers to the usage purpose of each user tool. For example, the way the user believes that a chat should work… Positive Anticipated Emotion: It concerns pleasant emotions that a user anticipates experiencing as a consequence of interacting with a user tool...

Improving IS (Information System) end-user experience is one of the most important tasks in the analysis of end-users behaviour, evaluation and identification of its improvement potential. However, the application of Machine Learning methods for the UX (User Experience) usability and effic iency improvement is not widely researched. In the context of the usability analysis, the information about behaviour of end-users could be used as an input, while in the output data the focus should be made on non-trivial or difficult attention-grabbing events and scenarios. The goal of this paper is to identify which data potentially can serve as an input for Machine Learning methods (and accordingly graph theory, transformation methods, etc.), to define dependency between these data and desired output, which can help to apply Machine Learning / graph algorithms to user activity records.
... This paper gives continuity and expands the research that we have previously published on this topic [36,37]. The objective of the present work was to know whether there are and which are the differences between User eXpectations (AUX) and the experiences they find on social networks (EUX). ...

Today, social networks are crucial commodities that allow people to share different contents and opinions. In addition to participation, the information shared within social networks makes them attractive, but success is also accompanied by a positive User eXperience (UX). Social networks must offer useful and well-designed user-tools, i.e., sets of widgets that allow interaction among users. To satisfy this requirement, Episodic User eXperience (EUX) yields reactions of users after having interacted with an artifact. Anticipated User eXperience (AUX) grants the designers the capacity to recollect users’ aspirations, assumptions, and needs in the initial development phase of an artifact. In this work, we collect UX perceived in both periods to contrast user expectations and experiences offered on social networks, in order to find elements that could improve the design of user-tools. We arrange a test where participants (N=20) designed prototypes on paper to solve tasks and then did the same tasks on online social networks. Both stages are assessed with the help of AttrakDiff, and then we analyze the results through t-tests. The results we obtained suggest that users are inclined towards pragmatic aspects of their user-tools expectations.
... Only two studies [8,36] use sensors, such as eye trackers, to identify the area that the user is observing. Almost half of the studies [1,2,8,32,33,[41][42][43][44][45][46] use some form of questionnaire to obtain qualitative information about user experience or usability. The vast majority of studies perform in loco evaluation, with the specialist observing the test in the same location as the participant, except for References [8,30,36], where the specialist remotely observe user interaction. ...

This paper presents UXmood, a tool that provides quantitative and qualitative information to assist researchers and practitioners in the evaluation of user experience and usability. The tool uses and combines data from video, audio, interaction logs and eye trackers, presenting them in a configurable dashboard on the web. The UXmood works analogously to a media player, in which evaluators can review the entire user interaction process, fast-forwarding irrelevant sections and rewinding specific interactions to repeat them if necessary. Besides, sentiment analysis techniques are applied to video, audio and transcribed text content to obtain insights on the user experience of participants. The main motivations to develop UXmood are to support joint analysis of usability and user experience, to use sentiment analysis for supporting qualitative analysis, to synchronize different types of data in the same dashboard and to allow the analysis of user interactions from any device with a web browser. We conducted a user study to assess the data communication efficiency of the visualizations, which provided insights on how to improve the dashboard.

Foreign language students must learn to use language creatively to overcome knowledge gaps and keep readers or listeners interested. However, few tools exist to support practicing this skill. Therefore, we set out to explore design of storytelling games for practicing creative language use. Through an iterative design process, we identified narrative grounding (establishing common ground for collaborative narrative) as key to student engagement and learning. However, designing games for narrative grounding while keeping the game flexible enough to easily accommodate teacher goals is challenging. Considering this challenge, we designed a collaborative storytelling game where students help scaffold the narrative and teachers can easily integrate language goals with "language cards". In an in-classroom evaluation with 36 students, we show the importance of narrative grounding for learning. Qualitative evidence also suggests narrative grounding makes the game more engaging for players. We conclude with discussion of design implications for digital language learning tools.

In the increasingly complex service environment, value is cocreated through webs of interactions between provider networks and customer networks. This is evident in healthcare services, where wellbeing can only be achieved through the joint efforts of professional healthcare networks and patient networks. Addressing the challenge of creating network-level services, Service Design for Value Networks (SD4VN) designs services as enablers of many-to-many value cocreating interactions among network actors. By integrating previous research on value networks and service design, SD4VN develops a process and a set of models beyond supporting dyadic (customer–service provider) interactions to understanding the interrelated activities, interactions, and goals of network actors and designing services to support the different actors in reaching their goals with balanced centricity. Following a Design Science Research approach, this paper presents the SD4VN method and reports on a case application of the method used to design the Portuguese National Electronic Health Record (EHR) service. The case application involved focus groups, in-depth interviews, and participatory design sessions with over 170 participants at different service design stages, showing the importance of designing a balanced, integrated service. The case application also shows how SD4VN can support a wider adoption of the service and improve the health service system.

In this paper we explore immersive street-level integration of social media content into collaborative virtual 3D city environments on two levels: i) public, where the virtual environment is populated with relevant social media content (e.g. Twitter and Facebook feeds of shops, non-governmetal organizations, the City organization); and ii) personal, where the virtual user, through his/her avatar, is able to access his/her personal social media feeds while immersed in the virtual city. We conducted a qualitative anticipated user experience study with 14 participants in four focus groups, who were asked to create designs of how they imagined social networking services could be integrated into virtual city environments. Further, participants were asked to comment on two visual concepts created by researchers. Results show that people appreciate the concept of having virtual cities populated with up-to-date content from social media services, but linking their own social media accounts is a more complex issue.

The paper motivates, presents, demonstrates in use, and evaluates a methodology for conducting design science (DS) research in information systems (IS). DS is of importance in a discipline oriented to the creation of successful artifacts. Several researchers have pioneered DS research in IS, yet over the past 15 years, little DS research has been done within the discipline. The lack of a methodology to serve as a commonly accepted framework for DS research and of a template for its presentation may have contributed to its slow adoption. The design science research methodology (DSRM) presented here incorporates principles, practices, and procedures required to carry out such research and meets three objectives: it is consistent with prior literature, it provides a nominal process model for doing DS research, and it provides a mental model for presenting and evaluating DS research in IS. The DS process includes six steps: problem identification and motivation, definition of the objectives for a solution, design and development, demonstration, evaluation, and communication. We demonstrate and evaluate the methodology by presenting four case studies in terms of the DSRM, including cases that present the design of a database to support health assessment methods, a software reuse measure, an Internet video telephony application, and an IS planning method. The designed methodology effectively satisfies the three objectives and has the potential to help aid the acceptance of DS research in the IS discipline.

This paper presents insights on driver’s User Experience (UX) in terms of systematically investigating predicted experience, actual experience, and recalled experience. By conducting a three-week field study with car commuters in two countries, we studied how frustration and anger differentiate in prediction, actual experience, and recall. Our results show that commuters accurately predict their upcoming anger or frustration in a traffic congestion, however, lower their experienced frustration when being recalled. Moreover, unexpected traffic congestions (in contrast to expected ones) are prone to higher levels of anger. We further found that time of day is related to the prediction of anger, and mood is related to the prediction of frustration. With our study we provide a holistic view on commuters’ everyday emotions and experiences – not only when being on the road, but also before and after the trip.

Providing a positive user experience (UX) has become the key for products to win a competition in mature markets. However, the early stages of product development have not been fully supported by current UX evaluation methods. We conducted a qualitative study investigating anticipated user experience (AUX) to address this issue. Twenty pairs of participants were asked to imagine an interactive product and anticipate their interactions and experiences with it. The data was analyzed to identify general characteristics of AUX. We found that while positive AUX was related to an imagined product overall, negative AUX was mainly associated with existing products. Furthermore, the hedonic quality of product received more focus in positive than negative AUX. The results also showed that context, user profile, experiential knowledge, and anticipated emotion could be reflected in AUX. The understanding of AUX will help designers to ensure pleasurable UX from the start of the design process.

Positive user experience (UX) is an important goal in product design. Positive long-term UX is believed to improve customer loyalty, therefore being vital for continuous commercial success. Most UX research investigates momentary or short-term UX although the relationship between the user and the product evolves over time. There is a need to develop methods for measuring long-term UX and evaluate their feasibility in different product contexts. In this explorative study, 18 customers reported their experiences during the first three months of use of a non-interactive design tool, an axe. UX was evaluated with retrospective iScale tool and monthly repeated AttrakDiff questionnaire. iScale demonstrated the long-term trend of the attractiveness of the product well and provided information about the causes of the change in the experience. The AttrakDiff questionnaire was a good indicator of attractiveness during a longer period of time and is also well suited to remote studies.

Player experience describes the qualities of player-game interaction and is typically evaluated during or after the game has been developed. Different approaches exist to improve and optimize player experience during the design process (e.g., design guidelines). However, the anticipated or expected player experience of users can also guide game developers and researcher in order to develop better games. A series of game ideation workshops with children aged 8 to 15 years was conducted in eight different locations around the world. The workshops produced video snippets, in which children explain their thoughts on possible game play scenarios of a game idea (i.e., anticipations and expectations). An initial content analysis of the videos highlights the game elements and playful experiences that contribute to the anticipated player experience of the children that should guide game developers and researchers.

Interaction experiences with public art installations are becoming ubiquitous recently, however, interaction is usually unidirectional and the actual experience not very rich. This work reports on an interactive public art installation aiming at increasing the level of social connectedness among visitors, and the results of evaluating the attractiveness of the installation. By connecting visitors and computers physiologically, the installation has clear impact on social interaction and it also shows the attractiveness to people from aspects such as creativity, novelty, inviting and motivating. In this work we also found that the AttrakDiff instrument to be useful and convenient in evaluating the attractiveness of public art installations.

Current literature has identified key components and successful factors of online communities. However, research tends to study a specific type of community at a time. This study investigates users' needs across different types of communities in order to gain a holistic view of users' experiences. Moreover, how the nature and overall purpose of the online community influences users' participation pattern has not been extensively studied. Hence, this study also attempts to understand how the nature of the community and the goals of the users influence their participation of online communities. Through twenty-four in-depth interviews, critical factors that influence users' participation in online communities were identified.

This paper presents an augmented reality environment for students' improved learning, which is based on unobtrusive monitoring of the natural reading and writing process. This environment, named SESIL, is able to perform recognition of book pages and of specific elements of interest within a page, as well as to perceive interaction with actual books and pens/pencils, without requiring any special interaction device. As a result, unobtrusive, context - aware student assistance can be provided. In this way, the learning process can be enhanced during reading with the retrieval and presentation of related material and, during writing, by the provision of assistance to accomplish writing tasks whenever appropriate. The SESIL environment is evaluated in terms of robustness, accuracy and usability.

Value co-creation is a core concept in service science. In this paper we investigate value co-creation to provide some answer on what is it and how can it be achieved. We take a customer-oriented perspective by focusing on the end-customer, the people that utilize services in their everyday lives to meet their personal needs. We consider that value creation is a social activity and we propose social networks as the basic infrastructure for the co-creation of value with business and other organizations, peers, relatives and friends.

This paper reviews how empirical research on User Experience (UX) is conducted. It integrates products, dimensions of experience, and methodologies across a systematically selected sample of 51 publications from 2005-2009, reporting a total of 66 empirical studies. Results show a shift in the products and use contexts that are studied, from work towards leisure, from controlled tasks towards open use situations, and from desktop computing towards consumer products and art. Context of use and anticipated use, often named key factors of UX, are rarely researched. Emotions, enjoyment and aesthetics are the most frequently assessed dimensions. The methodologies used are mostly qualitative, and known from traditional usability studies, though constructive methods with unclear validity are being developed and used. Many studies use self-developed questionnaires without providing items or statistical validations. We discuss underexplored research questions and potential improvements of UX research.

A recent trend in Human-Computer Interaction (HCI) research addresses human needs that go beyond the instrumental, resulting in an increasing body of knowledge about how users form overall evaluative judgments on the quality of interactive products. An aspect largely neglected so far is that of temporality, i.e. how the quality of users' experience develops over time. This paper presents an in-depth, five-week ethnographic study that followed 6 individuals during an actual purchase of the Apple iPhone". We found prolonged use to be motivated by different qualities than the ones that provided positive initial experiences. Overall, while early experiences seemed to relate mostly to hedonic aspects of product use, prolonged experiences became increasingly more tied to aspects reflecting how the product becomes meaningful in one's life. Based on the findings, we promote three directions for CHI practice: designing for meaningful mediation, designing for daily rituals, and designing for the self.

The recent shift of emphasis to user experience (UX) has rendered it a central focus of product design and evaluation. A multitude of methods for UX design and evaluation exist, but a clear overview of the current state of the available UX evaluation methods is missing. This is partly due to a lack of agreement on the essential characteristics of UX. In this paper, we present the results of our multi-year effort of collecting UX evaluation methods from academia and industry with different approaches such as literature review, workshops, Special Interest Groups sessions and an online survey. We have collected 96 methods and analyzed them, among other criteria, based on the product development phase and the studied period of experience. Our analysis reveals development needs for UX evaluation methods, such as early-stage methods, methods for social and collaborative UX evaluation, establishing practicability and scientific quality, and a deeper understanding of UX.

This paper concerns the relationship between agents or multi-agent systems and distributed communities of practice. It presents a review of a number of agent and multi-agent applications with features that could contribute to supporting distributed communities of practice. The association is promising because of features like autonomy, pro-activity, flexibility or ability to integrate systems that characterize agents and multi-agent systems. Furthermore, such an association is a step towards building mixed communities of humans and artificial agents. To understand how agents and multi-agent systems could answer some of the needs of distributed communities of practice, we organize the analyzed applications into five different categories defined by considering the main activities of a community, namely: Individual Participation, Synchronous Interactions, Asynchronous Interactions, Publishing and Community Cultivation. Such a classification helps us identify the relevant features of the current technology and determine some that should be further developed, e.g. to support community coordination or gather information related to virtual communities. For each application we selected, we present its main approach and point out its potential interest.

Using the information systems lifecycle as a unifying framework, we review online communities research and propose a sequence for incorporating success conditions during initiation and development to increase their chances of becoming a successful community, one in which members participate actively and develop lasting relationships. Online communities evolve following distinctive lifecycle stages and recommendations for success are more or less relevant depending on the developmental stage of the online community. In addition, the goal of the online community under study determines the components to include in the development of a successful online community. Online community builders and researchers will benefit from this review of the conditions that help online communities succeed.

Understanding virtual community development provides a foundation for facilitating collaboration and learning among individuals separated by physical distance and organizational boundaries. Migrating offline communities into online virtual communities has the potential to significantly improve their efficiency and ability to support the sharing of critical information and knowledge in a timely fashion. A virtual community can be seen as a group in which individuals come together around a shared purpose, interest, or goal. Typical computer-mediated community interaction includes news and information sharing, and routine communication. Four stimulation driver are proposed based on prior studies of the challenges and stimulants in virtual communities consisting leader involvement, offline interaction, usefulness, and IT infrastructure quality. More complex strategies for reinforcing virtual communities should be explored, as they are more used for collaboration and social support.

Introduction Tagging, or using keywords to add metadata to shared content, is gaining much popularity in recent years. Tags are used to annotate various types of content, including images, videos, bookmarks, and blogs, through web-based systems such as Flickr, YouTube, del.icio.us, and Technorati, respectively. The popularity of tagging is attributed, at least in part, to the benefits users gain from effective sharing and from organization of very large amounts of information. As tagging receives increasing attention in both research and business communities, studies have found that users vary substantially in their tag usage, and suggested several factors that motivate user tagging. However, to date no quantitative study has assessed the strength of the effects of each motivation on levels of tag usage. This is surprising, since user participation is critical to the sustainability of content sharing communities, and a collaborative tagging system cannot succeed without higher level of user contribution. In what follows, we address this gap, by studying the strength of relationships between several motivations and users' tagging levels on Flickr, a prominent Web 2.0 photo sharing community. Currently, there are more than 35 million Flickr users, who have so far uploaded more 3 billion photos. Each Flickr user can upload images and make them viewable by self, by designated friends and family, or by all Flickr users. Flickr users can annotate images with tags - unstructured textual labels; and usually images are tagged only by the user who uploaded them.8 These tags make the images searchable by the uploading user, as well as by others. In addition, each user can designate other users as "contacts," people whose photos the user follows (contacts are often reciprocal). To understand what underlies tagging, we need to find out what motivates sharing in online environments, and in particular, what motivates tagging. Furthermore, we need to measure the degree to which different motivations affect tagging activity. While some studies has identified individual-level motivations for tagging, other studies have looked solely at the social level, focusing on the social presence as a driver of tagging.

Virtual communities are not only used to share information among their members with common interests, but also an avenue of entertainments, networking with friends, and shopping. Recently, the main research topics on them include social networking, success factors, reasons for participating, and consequences from joining in virtual communities. Relative few works to discuss what important quality factors are for attracting customers to join the virtual community websites. From the viewpoint of increasing margin of websites, to identify important quality characteristics for attracting more internet customers in virtual community is crucial for website enterprisers. In this study, we attempt to define the quality factors of virtual communities and then identify the key factors for attracting new members by using a feature selection technique. In addition, the importance-satisfaction model was also implemented for analyzing the collected data further. Finally, a real case study of "Facebook" has been provided to evaluate the effectiveness of the used methods.

Constant monitoring of road conditions would be beneficial for road authorities as well as road users. However, this is currently not possible due to limited resources. This is because road condition monitoring is carried out by engineering companies using limited resources such as specialized vehicles and trained personnel. The ubiquity of smart devices carried by drivers, such as smartphones and the ever-increasing number of sensors installed in modern vehicles, makes it possible to provide information about the condition of the road on which the vehicle is driving. We develop a smart, crowd-based road condition monitoring service that establishes an intermediary between the crowd as data provider and the road authorities and road users as service customers. In addition to providing customers with accurate and frequent road condition information, subscribers can monetize their collected data. We prove the feasibility and usability of this smart service through analytical and descriptive evaluations.

This study examined the determinant of continuance intention of Facebook usage among female library and information science (LIS) undergraduates selected from Four Library Schools in the Nigerian universities. Survey design approach was adopted and Questionnaire was used for data collection. Collected data was analyzed using percentages and frequency count; multiple correlation and regression. The results revealed that the inter-correlation exist between the dependent variable (continuance intention of Facebook usage) and the independent variables (i.e. Peer Influence, User Friendliness, sense of belonging, perceived enjoyment, Satisfaction, security, Facebook interface quality and attractiveness and perceived benefits) and jointly as indicated by the R-square value explained or predicted 49.4% of the variations in the LIS female undergraduates continuance intention of Facebook usage. The result generally suggests that the entire continuance intention dimensions/factors significantly correlates with Facebook continuance intention.

Virtual communities (VCs) evaluation research looked into different aspects of evaluation such as usability, effectiveness, and impact. However, these measurements do not take into account some particularities of the Health Virtual Communities (Health VCs), such as the impact of the patient’s health condition on software usability and the effect of the Health VC on health outcomes. In this chapter, we give an overview of existing literature related to VC evaluation, and summarize the main VC evaluation limitations and challenges, particularly the need for a framework for VC evaluation. We then look into the available frameworks to evaluate information technology and information systems and their ability to VCs, and then lay out the need for a framework to evaluate Health VC.

Consumption-based virtual communities are nowadays a common place on the Internet where individuals share and acquire knowledge on food and specific food-related issues such as preparation and cooking. The objective of this research is to propose and test a model that illustrates the role of motivation to self-present to and learn from the community regarding consumers’ willingness to interact in virtual food communities. The study investigates 1) the associations between the pre-existing consumer interests in food and general online interaction, and consumers’ willingness to interact in virtual food communities, and 2) the mediating role of consumers’ motivation to self-present to and learn from the community in explaining these associations. An online questionnaire (n = 980) was conducted among Danish consumers. Results showed that motivation to learn and motivation to self-present are strong mediators of the relationships especially between food involvement and behavioural interaction intention. The chance to learn from and present oneself to the community are reasons why consumers engage in interaction in virtual food communities, given their pre-existing interest in food and, to some extent, their general online interaction propensity. Virtual food communities should therefore provide consumers with the opportunity to present themselves as skilled individuals to the community and the opportunity to learn from the information available from that community. Still, community managers must keep in mind that these opportunities will only appeal to food involved consumers with a certain online interaction propensity.

Through Online Social Networks, like Research Gate, Stack Exchange or Facebook, it’s easy to find a partner for cooperation, because Social Networks have the potential to connect thousands of people. To assist finding the right person for cooperation many of these networks have Recommender-Systems, but these systems mostly rely on the matching of keywords for each individual. This article shows on a conceptual level, that current Recommender-Systems for cooperation on Online Social Networks can be improved by additionally using personality for recommendations. Methods like Language Inquiry and Word Count (LIWC) can help to achieve this goal by presenting methods for an automated calculation of personality from user- generated content in these networks, without the need of questionnaires. Based on personality different cooperation types can be derived to improve recommendations for cooperation partners, leading to a better cooperation and therefore help to increase cooperation in Online Social Networks.

Nowadays, the induction of positive user experience is a vital aspect of the development of smartphone applications. Existing approaches aim at engineering good user experience to make applications more enjoyable and pleasurable. Especially in business applications, employees need to be motivated to perform their tasks, in order to increase efficiency and effectiveness. Negative user experience lowers user acceptance and decreases motivation. A study was conducted to identify factors that can cause negative user experience. This study found negative aspects of an example mobile application, of which Usability and Utility have been found to directly contribute to a negative Emotions and thus to negative user experience.

By examining the Empty Plate Movement, a campaign advocating food saving in China, this study compared proactive engagement activities by traditional and virtual opinion leaders, organization advocates, and other participants. Specifically, this study focused on three proactive engagement activities: publishing descriptive and injunctive normative messages and messages showing supportive/adoptive behaviors. The findings reveal organization advocates are the most likely source of descriptive and injunctive normative messages, and the least likely source of messages showing adoptive/supportive behaviors. Virtual opinion leaders are the most likely to publish messages showing adoptive and/or supportive behaviors. Both message features and message sources influence users responses. The findings suggest that organizations practice strategic communication in advocacy. Because of their motivations for self-involvement and online interaction, virtual opinion leaders frequently publish messages about their supportive/adoptive behaviors. The strategic value of SNSs lies in the mimicking process. Practically, this study suggests that virtual opinion leaders and organization advocates are useful to advocacy campaigns on SNSs.

The important role that consumers play in virtual communities as active participants in the value co-creation process has been increasingly acknowledged in recent marketing thought and practice. This study applies and extends the well-established value–attitude–behaviour (VAB) model to investigate how personal values and personality jointly influence consumers' attitude and behaviour towards their participation in virtual communities. The results show that while the resultant conservation value dimension has an indirect influence on consumer participation behaviour in virtual communities through attitude, the extraversion trait has a direct effect. The findings clarify our understanding of how personal values and personality differently predict consumer participation in virtual communities, and confirm the role of personal values and the VAB model in explaining this phenomenon. This study suggests significant implications for virtual community marketing.

Little attention has focused so far on evaluating the success of online communities. This paper starts to identify some key determinants of sociability and usability that help to determine their success. Determinants of sociability include obvious measures such as the number of participants in a community, the number of messages per unit of time, members' satisfaction, and some less obvious measures such as amount of reciprocity, the number of on-topic messages, trustworthiness and several others. Measures of usability include numbers of errors, productivity, user satisfaction and others. The list is not exhaustive but it is intended to provide a starting point for research on this important topic that will lead to develop of metrics. To avoid creating false impressions it is advisable to use several measures and to triangulate with qualitative data, particularly from ethnographic studies.

Purpose The purpose of this study is to examine the determinants of online community user participation from a social influence perspective. Design/methodology/approach Based on 450 valid responses collected from a survey questionnaire, structural equation modeling (SEM) technology was employed to examine the research model. Findings The results show that both social identity and group norm have significant effects on user participation. In addition, group norm affects social identity. It was not possible to find the effect of subjective norm on participation intention. Research limitations/implications This research is limited to a particular sample: students. Thus the results need to be generalized to other samples, such as working professionals. Originality/value Extant research has mainly focused on the effects of user motivations such as perceived usefulness, trust and commitment on online community user behavior, and seldom considered the effects of social processes including compliance, identification and internalization on user behavior. This research tries to fill the gap.

What makes online communities successful? There are many indicators of success. Some are easily observed and measured, such as the number of people registered in the community, or the number who participate, or the number of messages posted, replied to or read over a certain period. How community members judge their community is also important. What do they like or dislike and how committed are they to the community? In this paper, we describe participatory community-centred development an approach that relies heavily on iterative evaluation. We then point out that standard evaluation techniques are inadequate for evaluating online communities because they do not address sociability. Finally, we propose two approaches from research that can be tailed for evaluating online communities. Both attempt to draw directly on what community users want. The first is rooted in ethnography and the second is a form of heuristic evaluation. The paper ends with an agenda for developing these approaches to make them practical yet robust.
