I’m not the only one who’s been messing with MediaWiki. AmbientLibrarian, at http://www.ambientlibrarian.org/ , is a wiki designed to keep librarians up to date with Web 2.0 technologies.
Categories include Blogs, Cool Tools, Digital Libraries, and, of course, Wikis. For those of you interested in Wikis and want to give ‘em a try, there’s a sandbox where you can practice your wiki editing skills.
No too much activity here — looks like the site’s less than a week old. Plenty of information, though, and a nice outline of categories.
