There is a new add-on for the massive online game World of Warcraft that lets players use Twitter from inside the game.
TweetCraft is an in-game Twitter client for World of Warcraft featuring sending and receiving Tweets in-game, Queue Tweets, Upload in-game screenshots using TwitPic, AutoTweet when you log in, and Extensibility, so that AddOn authors can register messages or events to AutoTweet.

As if Twitter would just need another huge user group, but here we go and Twitter will grow again with this connection. According to Hitwise, the site is now the fifth most viewed social networking site. As reported Twitter does not like it when 3rd party tools use Tweet or Twitter in the naming of there tool. I say, forget about it and just appreciate the fact that these tools bring the traffic and make Twitter a highly valuable platform.
TweetCraft can be downloaded from Codeplex. Via GamesIndustry.biz.
