Not only do I think it is a relatively nascent and potentially useful idea, but the idea of combining interactive video type games and knowledge discovery is proving to be quite useful in scientific pattern discoveries.. such as 'foldit,' a game designed to discover folding patterns in...

I just used this post.... Granted, from post to post, there's very little consistency in his numbers.

~2 bill. Incidentally, there's a simple equation to get the results. p0*(1+rtn)^nyr here, 368*(1+.6)^33 ~ 2e9 30yrs would get you to around 1/2 bil (as long as we're dreaming).
