At HOPE Number Nine in 2012, James spoke to people about how to build community infrastructure to provide support at a scale larger than just one project at a time. Then he went and built some. This talk is about lessons learned - how to replicate the successes and avoid the failures he's experienced in the last two years. The focus will be on his two case studies: 1) the formation of a localization community for anti-censorship and anti-surveillance tech (which went reasonably well) and 2) creating a heavier-weight code auditing organization for anti-censorship and anti-surveillance tech (which had some hiccups). There are lessons in both and they will be the basis of discussion here. The goal is to also seed some ideas on how to build this kind of infrastructure for other niches and the wider free software community.
