Ssshhh...apparently, it's some kind of secret.

Win a live one-on-one talk with Guy Kawasaki or Warren Farrell, or a personally autographed book from Sir Harold Evans or Anne Fadiman, or CD from Bela Fleck, or an iPod Nano!

As of this posting, the iPod Nano is already going for well above retail price (though it is for Katrina relief), but other celebrity-related items are going pretty cheap.
