It is a really interesting question if GitHub is a social network. As the author points out there are many social aspects such as social currency (stars), or is it merely gamification? Colleagues can ask you to review code or ping questions - definitely social, but could you then say Jira is a social network? Overall I do think GitHub is a social network, but that is because the definition has broadened to include a lot of 2-way group communication tools.
