LOL, WIM. You keep just beating me out... first you posted the announcement about 5 seconds before I did, then you replied to my post with Costello's tweet 5 seconds before I replied to your post with the same. Great minds or something.
Drukarev just retweeted someone saying "Stanford got 2 commits..both game changers". One of the two game changers is obviously Costello, but did I miss the second? All the talk here is about Costello.
