What is so sad about it? Are you also saddened by the fact that are few blacks/hispanics/[ethnic]?
Well I suppose it's not quite as necessary evolutionarily to socialize with "blacks/hispanics/[ethnic]" as it is with women.
I agree with you - I don't get this 'not enough women in tech' thing. If something is predominantly gender specific then does it matter? I don't see anyone actively discouraging women from being involved, the plain simple fact is that most aren't interested!
