MeatballWikiwiki dedicated to online communities, culture and hypermedia. Its original goal was to focus on collaborative hypermedia but topics have ranged from intellectual property to cyberpunk to the confusion of URIss.
MeatballWiki also hosts various project journals. In particular, it has influenced much of the design of UseModWiki.
Because of its role as a community about communities, it has become the launching point for various other wiki-based projects, and a central resource for the wider wiki community. While its aims do not explicitly include becoming a centre of this community, the content it produces is well-suited to use as reference materials elsewhere.
