Ask YC: Missed Opportunites at YC

I don't know of any so far. There are bound to be eventually, though.

Well, unless you're hotmail or YouTube, it takes more than 2-3 years to be "really successful". YC has only been around for something like 3 years. Give it some time.

What about other places such as TechCrunch 40?

I love the idea, but the site looks horrible in IE7 (lets not get into the reasons I'm using IE7 right now ...)

With all due respect to their work, I don't think that its an IE7 problem.

Google applied to Y Combinator but was rejected.
