Welcome to the first issue of the Journal of Peer Production (JoPP). The journal has been created to further the study and critical discussion of the concept of peer-to-peer. What is meant by that term is precisely one of the questions we wish to investigate here. Provisionally, we define “peer” or “collaborative” production as a mode of commons-based and oriented production where participation is voluntary and predicated on the self-selection of tasks. Starting from this ideal type, we set out to scrutinise the inconsistencies and contradictions of peer production. Our aim is to add a new kind of forum for discussing the concerns, aspirations and fears that have been fermenting on the Internet for close to a decade. The journal format will hopefully allow for a more sustained and focused investigation of these topics, while increasing their visibility in academia and in offline society. The genesis of the Journal of Peer Production occurred at the Fourth Oekonux conference in Manchester in 2009.
