While I believe in all of YC's efforts to integrate women, I feel like one of the hurdles that they are ignoring is convincing the men. What do I mean by this? I mean that statements like "We want to fund more women because we are greedy in the good way," I believe in 100%, but not because I have some facts to back it up. YC, on the other hand, should have numbers and facts to back this up and I think it would make their statements that much stronger. Now, you might ask, why is this important if the goal is to attract more women to startups? The answer is that you want the women who do come to be playing on an even playing field: the VC's in the industry are still largely dominated by men. If you can convince them with numbers that they are doing the right thing by not having a bias against women, the women who try to raise money will do it more successfully and then encourage more women to try.
The best way to convince people is through examples (the total number of companies YC has funded is small enough that a few females who are highly successful would be statistically significant).
None are at the AirBnB/Dropbox/Stripe/Heroku/Reddit/Parse/Polvi stage yet, but everyone in YC knows of a few female YC participants who seem to be on the same trajectory.
