I want to introduce a new side project that I have been pursuing together with my friend Matt Libo-on: Wikindex.com is an index of wiki sites. We spider through the statistics of sites running mediawiki software, and gather the daily usage, size, and number of users. These statistics should show a searcher which wikis are active, and which ones are dormant. For example, if you search for “linux”, you’ll see three or four entries, with one (Gentoo Linux Wiki) showing a huge number of articles and users. This is the active one, and probably the best source for information.
On a lighter note– who knew that the wiki for Star Trek is bigger than the wikipedia in over half of the European languages? Those trekkers are nothing if not well-versed.
