Just wanted to echo this. 99% of the hackers/programmers/whatever I've met, whether in industry or at university have been pretty normal. In fact, the cleverest and most productive ones have tended to be more socially successful, not less. Tech people I've met actually tend to have more enlightened views on women/gender than the population at large.
Where it does start to get weird, in my experience, is when it starts to cross over into the gaming/anime/fandom area, particularly gaming. Some of those people are really maladjusted, but I suppose that's to be expected from a subculture based around endlessly celebrating childrens toys.
There must be some generational/geographical divide here somewhere. For reference I'm in the UK.
