I agree, I think YCombinator is great and they need to find a way to "foster" the growing community of mini start-ups who are perhaps, not yet ready for incubation, or don't need it, but are still capable of realizing their potential. This community should be free for all, in order to meet, network, collaborate, learn and keep passions burning. Focus on investment potential could be secondary to focus on start-up community growth, involvement, and learning.
