Perhaps you want to discuss online communities, but do so in an environment with different values, people, ideas, software, etc. So, a few options: (Which of these do not demand UseRealNames?)
- Wiki:WikiOnWiki
- MetaWikiPedia (particularly discussion relating to wikipedia and other wikimedia-supported projects)
- CommunityWiki
- CraoWiki (in LangueFrançaise)
- GründerWiki (Deutsch)
See also the WikiNode.
If you're mainly interested in reading about online communities, rather than discussing them, here are a few interesting places to read:
If you want to discuss something other than online communities that is covered on MeatballWiki:
- IaWiki for InformationArchitecture
- [ESW Wiki] for W3C discussions of the SemanticWeb.
- [InfoAnarchy Wiki] for those interested in remaking IntellectualProperty law. (Update: Wiki is dead since around August 2020. Here's the last good archived version of its Main Page: http://web.archive.org/web/20170914022124/http://infoanarchy.org/Main_Page
- http://wikifeatures.wiki.taoriver.net an index and discussion of wiki features. (Update: Dead between 2008 and 2014. Last good archived version: http://web.archive.org/web/20080915101830/http://wikifeatures.wiki.taoriver.net/
- [GetMeta] for discussions of Philosophy, technology and other "metatopics".
