Though...what happened last time was that a lot of insightful long-term contributors were accepted and then disappeared off the face of the site while they worked on their startup. Meanwhile the folks leftover were all the ones trying to make themselves look good to YC at the last minute.

Eventually it rebalanced out. The short-term folks got bored and left, while a new crop of top posters grew out of the ones who weren't ready for YC as of the summer but were going to become startup junkies anyway.
