As the West loses its political credibility, the search has opened for alternatives to neo-liberal parliamentary democracies, failing on their own scale of good governance. Several contemporary critical thinkers, such as Alain Badiou, turn towards a communist horizon. In this paper, we want to explore the idea of commons in contemporary Internet-based groups, as a quest for contemporary appearances of communism in the Badiouian sense. From wiki formats to the hacktivism of Anonymous, there are various Internet-based initiatives that are built (...) on a philosophy of open access to all, regardless of their identity, and a horizontal, rhizomatic organisation. We think that the organisational features of these initiatives make them suitable to carry out a struggle for new, more democratic political alternatives. (shrink)
