This just came to us from the folks at groups.im and looks like it could be an important development on the twitter scene.  With the popularity of MSN instant messaging platform, it is not only bound to be interesting to many Twittown readers, it may have the potential to bring twitter + MSN to millions of mainstream people that rely on using MSN messenger daily. 

It also brings up the question of if Microsoft should buy twitter.  They could integrate it to their MSN client and get hundreds of millions of users using twitter.  Even more importantly, they would own the real time stream and could own realtime stream search by integrating to Bing.  Thoughts to ponder anyway.

Coming back to the topic of this post though, TwitOnMSN is described below.  We haven't as yet tested or reviewed the service so let your fellow Twittown readers know by leaving your feedback in the comments if you have a chance to try it.
