This paper examines how Scholarism, a SMO found by a group of secondary school students, appropriated social and digital media for a ten-day occupation protest against the “Moral and National Education” curriculum, imposed by the Education Bureau in Hong Kong. Drawing on research that recognizes the more scalable organizational forms and communication networks enabled by NICTs and the notion of appropriating technology, I analyze the ways that the SMO employed non-hierarchical channels for mobilization, and created ad hoc political alliances for collective action. This paper provides insights into the changing communication-related mobilization processes of new activist groups adapted to the new media environment.
