On October 29th, Charlie Schweik gave an invited plenary talk entitled “Reflections on Open Source Software and Open Science Peer Production” at the “Seventh International Workshop on Network Theory: Peer Production Networks” at Northwestern University. In his talk, Schweik presented findings from his large-scale empirical study of open source software as the ‘quintessential instance’ of peer production, and then reflected on his work in peer production in other domains, such as open educational resources and in open source hardware and science.
