A variety of social movements across the world and the political spectrum are now taking advantage of peer production mechanisms such as collaboration, co-production, and self-organisation. This essay investigates the consequences of peer production for social protest, looking at how peer production reshuffles and remediates social change activism today. It explores the convergences and tensions between peer networks and contemporary social movements ranging from informal coalitions and amorphous grouping to traditional social movement organisations. First, it traces the historical trajectory of peer production as it has come to permeate the progressive social movements of the last three decades, linking distinct approaches to organizing to technological innovation. Second, it reflects on the so-called social affordances (and constraints) of digital infrastructure and their role in fostering specific modes of creativity and convergence apt to support protest actors. Third, it explores three types of consequences of peer production for social movements, namely cultural production and norm change, collective identity, and the commons. The chapter then examines three tensions that might emerge in the process of embedding peer production mechanisms and values in instances of collective action, namely: individual vs. collective engagements, peer networks vs. social movement organizations, and self-organized vs. commercial infrastructure.
