Julia Lerman talks about the general lack of women in the software development business: (in the context of an MS MVP meeting)
She brings up an interesting point about the very young MVPs - teens and college students. The only college age MVP female I know is Stacey Yasenka from Ohio. I met her when I kept asking isn't there even ONE girl in the Student Ambassador program. She now proudly tells me there are three! But there were even some highschool boys
This is a general issue in software, hardly limited to the MS side of the development house. I don't think it's a sexism thing at this point in time - most guys I know would love to have more women in the mix. No, this seems to be one of those subtle sorting things, like you see at parties. Go to a party with a bunch of married couples that know each other - over time, the men and women will tend to separate into their own groups, talking about their own subjects of interest. I've seen this for too many years to think it's a coincidence :) It looks to me like software development is one of those fields that women tend to sort themselves away from. Why? Heck, darned if I know. I just know what I see.
