Making the two top tiers be sponsorships is interesting. Those raised about half the total so far. I wonder if anyone was thinking, hey, this is a pretty cheap way to get good visibility. Especially the $1000 city sponsorship, since you can just pick big cities like NYC.
I was wondering about that. I guess picking the cities would be on a first come, first serve basis... which could get ugly if you find out you can't pick your favorite city -after- you've spent $1000.
