The video isn't up yet, but according to TechCrunch's own Alexia Tsotsis,
Let me save you a recap of a lot of the bitching. Basically there's one female contingent that thinks the lack of female startup founders is due to lack of awareness of the lack female startup founders and there's another female contingent that thinks that the lack of female startup founders is due to the fact that women do not start up startups. Whew!... Basically reasons for why there isn't more women in our industry are well known and much discussed, primarily the lack of role models for women who are interested in tech.
If you're wondering why Tsotsis sounds a little defensive, it's probably because her boss, Michael Arrington, felt personally singled out when a quote in a women in tech story used his conference as an example, and fired off an angry post saying that women had to stop blaming him. Said caller-outer, Rachel Sklar, was on the panel today. (Apparently her age became an issue.)
