In this article we examine the different forms of activism using information and communication technologies for representation of different political positions. Within the framework of radical democracy (Laclau & Mouffe 1985) we develop a typology of contemporary activism. The results are based on three qualitative case studies of political activism where digital communication played an important role: [1] middle-class activists in Sweden fighting to save their bathhouse; [2] student protests in Austria; and [3] anti-fascist protests in East Germany.
