This chapter explains how the communities formed through social networks can be understood in relation to free time cognitive surplus and the dissolution of the boundary between public and private immobile socialisation which have a major bearing on the weak social integration of the individual in the group and the ephemeral nature of the community itself. Based on cultural creativity and political activism, put forward a methodological framework focused on the study of two criteria that seem to be central to activist expressions of cultural content in the digital world. This contextualisation, added to theories of communication, studies of changes of paradigm and the analysis of recent history, help to understand the present context when discussing online political activism and earlier theories of media representation, media politics and new languages. This chapter develops a reflection that would help to explain the emergence of cultural projects created by political aspirations in the collaborative environment of Web.
