This talk offers a preliminary analysis of the technological affordances and use of Rousseau, the decision-making platform of the second largest Italian political party, the Five Star Movement. Crossing an empirical observation of the platform’s functionalities with data regarding its use and qualitative data collected during the last National Meeting of the Five Star Movement, it will argue that Rousseau supports an emerging “direct parliamentarianism,” which allows party members to entertain an ostensibly direct relationship with their elected representatives. The emphasis on the decisional moment, however, is not supported by an equal emphasis on deliberation, which is virtually absent from the platform and confined to applications and events (such as Facebook, beppegrillo.it, and Meetup groups) that are not integrated with the platform. In compartimentalizing deliberation and decision-making, Rousseau tends to separate what Chantal Mouffe calls the political–that is, the unfiltered antagonisms that exist within society—from politics, understood as the institutional framework within which these antagonisms are channeled and regulated
