Networks for cyberactivism have been developed in Brazil since the end of the 20th century. This chapter presents results of a three-year research about networks for digital political participation developed by civil society. The research analyzed 41 networks according to specific analytical categories to deepen the understanding about their potential to foster citizens' engagement in political initiatives and strengthen democracy. Several mechanisms that considerably stimulate a culture of political participation were clearly observed. Possibilities for political acting through those networks tend to narrow the gap between citizens' claims and government actions but that is not always the case. There is a lack of synergy between citizens' demands and strategic planning of public policies and other political outcomes. Some hypotheses are discussed to understand this context and reflect on the trends and challenges to digital democracy in the twenty-first century.
