Ask YC: Where are the Other Opportunities?

Now that we're all past the decision-making process, I'm curious as to what other places there are that are somewhat like Y-Combinator. Anybody got some links?

I hope it's appropriate to ask that question here. I don't have a personal need for the information right now (my application was a lark anyway) but I know others might find it useful. And it's something nice to have in your back pocket for the future,right?
