Dr. StrangeTweet, or: How I Learned About Martian Ice By Social Networking

I can finally provide one, concrete reason I really do like Twitter.

June 19, 2008 -- Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it.

I saw that news almost immediately after it was posted because I follow MarsPhoenix. Of course, I then saw it several more times as people re-tweeted the incredible (though tentative) discovery.

Of course, I also knew when Matt Fraction went to take a leak last night, so it's not all earth-shattering information.
