What's with the downvotes, people? I agree that Karma points shouldn't be used as a reward, but I think most people here participated because guessing/estimating value of a lunch with pg was a challenging and fun thing to do. Now, is that against HN spirit? Does it deserve a punishment? Relax, geez.

I guess the reason is this: OP has asked a specific question to Paul with a specific answer. Why do we need predictions here?
