We talk a lot about the wiki community on our blog and elsewhere because we really feel part of it. We wanted to give you an idea of where we feel like we belong in this community. This isn’t a complete chart of wiki relationships, or even our own relationships. The version below leaves out Tikatu, who has been involved with TVTropes, Girl Genius Wiki and Wikipedia as a contributor.
Lots of connected parts. AboutUs, wikiHow, Wikipedia, EncyclopediaDramatica, Wikia all have play an important role in shaping our policies, our concept of content organization and adding content. We talk to founders, contributors, assist on many of the wikis on this.
