state of the wiki
You can write wiki bots to communicate with MediaWiki via APIs. I do some of this with User:VoidBot, and Nat has also done some. If you start working on any wiki bots, let me know and I can give your bot user the "Bots" permission (if you promise to be careful =)). Darkcanuck's RoboRumble server also has an API you can play with: Darkcanuck/RRServer/Query.
