In this paper we propose an analysis of net-activism practices, and how they influence the cultural change process of protestors in the citizen riot of Oaxaca (Mexico) in 2006. The approach adopted in the research is “bottom-up”, hence just analyzing the movement itself. This aspect is both methodological and theoretical. In the analysis of the net-activism’s practice, we focus on the emotive dimension of protestors. The analysis of the emotive components allow us to explicate the initial motivations of collective actions, and how new media are linked with citizen empowerment
