Found this on the PA Report.

It seems like a great era for women who want to become famous in gaming culture-- but only if you want to be famous for anything but your gaming skills. Since there are a minority of women as well as an apparent lack of sex in gaming culture, any kind of woman who chooses to use sex appeal in her approach can quickly gain personal wealth and fame (that is, if she's traditionally attractive).

However, any woman that wants to game competitively and only that has to face much worst than her male counterparts. This is both because of the fact that most prominent women in the gaming culture, do go into it with boobs blazing (rather than guns, I guess) as well as the fact misogyny is unchecked in a male-dominated culture.

In short, it really sucks if you're female and want to game competitively. Once you get in the limelight, people will discuss your fuckability or question your legitimacy, rather than acknowledge your gaming abilities for what they are.

EDIT: The discussion in the comments section of the PA Report is really discouraging. I find that much of Penny Arcade's following are exactly what they are trying to counter. I wrote my own bit in the comments here:
