Dunno. But OTOH, I've sure seen unqualified women being hired "to counter gender inequality".

I don't know any women in CS. But analogizing from my experience in the legal profession, I think it's a huge practical concern for women. When my female friends were looking at what firms to take jobs at, they very heavily weighed statistics like the percentage of female partners. My wife accepted at her firm partly because one of the departments she was interested in was female-dominated--had a large number of female associates and a "critical mass" of female partners that brought in their own business and had pull within the firm.

Being a minority sucks, and ambitious people realize that in any organization getting to the top is as much about social ability and politick-ing as it is about ability. Working as a woman in a male-dominated culture may have zero impact on your work, but it's sure as hell going to have an impact on how easy it is for someone to form work relationships and leverage them to get ahead in the organization.
