Where'd you get the "accepting 25" number? Just curious. It seemed like 19 was a bit overwhelming for them this time. But since the CA office is bigger, and there are more former founders out here that would be able to relieve some of the advisory role pressure, they might be willing to bump the number up again, assuming enough of the applications are good.
Maybe even more than 500. [link eludes me] But somewhere it was written that the Cambridge session was the unpopular session. And since May 2007 YC has been featured in Newsweek, in addition to getting a groundswell press from each individual company (eg. Weebly in Time).
