Reading this article I thought about two things:

1) This guy is a real entrepreneur. He made a deal. I am thrilled! Congratulations! :) Reminds me of the book from Donald Trump about the deals.

2) Y Combinator partners are undoubtly clever people and they can't afford themselves to apply each pitch or idea and you should look for a hack to stay out of the overall group to be noticed and given a chance to win or fail.
