I'm looking forward to using them for some of our open source meetups.
As for your second question, this is definitely not just aimed at big brands. We've had dozens of small brands who are entering a market for the first time, and have no idea where to start, approach us about putting together a sponsorship campaign for them.
their site looks amazing though, this area seems to be maturing quickly, with sponsorhub.com also in the ring.
It's not clear to me who the winner is, but I'm going to list on all 3 sites when it comes time.
