I think this is more a result of the increase in acceptance of entrepreneurship as a career option. Adding to the list of predictors of a tech correction, when you have a bunch of investment bankers and management consultants coming into consulting, you know you've peaked.

I have to wonder, what's the catchet of YCombinator when you have so many new startups being churned out every quarter? YC is always going to be fine - they get their 7%. They're simply increasing the bandwidth and they'll get a few hits, but we should be prepared for the average quality of YC start-ups to fall with volume.
