I said parts of the YC universe have a reputation of being uncomfortable with women. It's an overwhelmingly-male environments and a lot of the guys who hang out in that world are more comfortable with men than with women. If you're trying to recruit women, you want to actively signal that you're not like that.
Thanks for the response. I was hoping you'd actually have an example. I'm not surprised that y-combinator seems to get the wallflowers when it comes to interacting with the opposite sex.
I'm personally comfortable hiring women just to bring different perspective to problems. I'd be champing at the bit if I were in the "social" space.
