This blog, the Department of Justice, is mostly the personal blog of Jack Phoenix, a MediaWiki developer and an open source enthusiast.
In addition to Jack, there are other people who will occasionally write a blog post, too.
Blog posts here will usually deal with issues related to wikis and/or open source. Another recurring theme is power abuse in the wikisphere, which is (sadly) a lot common than one might think.
If you want to suggest something for us to blog about or just discuss with Jack, please e-mail jackcountervandalism.net.
