"TweetCraft is an in-game Twitter client for World of Warcraft, the wildly popular massively multiplayer online role-playing game by Blizzard Entertainment. If you're a WoW player you might like it because you can send and receive tweets in-game, upload screenshots to TwitPic, automatically tweet when you get an achievement, and more. Also, the overly dramatic video promo is fun."
