Tweets from space

Ever since I read this New York Magazine piece back in February, I've been intrigued by Twitter, but haven't latched on. I've had trouble understanding why it would be a good addition to my arsenal of Interweb distractions. Friend updates are cool, but Facebook has that. And so what if John Mayer had salami for lunch? If Oprah's having a bad hair day? But this is officially fuckin' cool:

NASA astronaut Mike Massimino is sending "tweets" from space. His first update:

"From orbit: Launch was awesome!! I am feeling great, working hard, & enjoying the magnificent views, the adventure of a lifetime has begun!"
