I wouldn't have just told Charlie Rose "All Hail Jessica Livingston" if her role were just "founder relations" -- without going into the roles all the partners (male and female alike) play in YC, that simplification is way off.

(1) First off, it's great that several YC founders are so quick to come to the female YC partners' defense, which lends a lot of credence to PG and JL's claims about the large role of female partners at YC.
(2) We all know that even the greatest product can be held back by poor marketing. I don't personally know the YC founders my friend above referenced (via my username), but the fact that some~many YC founders would think that at all, shows that there's a lack of good marketing/branding around how active and influential women (i.e. JL/KN/CL) are at YC.
The (positive) reality clearly does not match the (negative) perceptions.
I don't know what the solution would be, and you could certainly argue that PG/JL/et al. shouldn't have to "market" or "brand" this aspect of YC at all, but clearly this a problem, especially in light of PG's latest essay, the Information/Valleywag incident, etc.
