The first round of the Digital Habitats Twitter Contest had 94 entries and the winner was:
Congrats Christy! I'm now a bit jealous as you are getting a book that's going to be sitting by your desk for many years and it's signed by John and Nancy.
I think that the contest has already been successful, but there's still another chance to win.

By the way, even if you don't win a copy of the book, you can still come hear Nancy and John at LearnTrends 2009. In fact, John is doing two sessions.
