Because your stereotypical computer geek doesn't have the social skills to meet women who aren't also computer geeks?
Because computer geeks don't push back hard enough against overtime requests (a social skills issue again), and so have a hard time meeting anyone they don't work with?
Because unlike many jobs, much of computer programming also makes for good hobbies, so we spend a greater fraction of our time associating with like-minded people (and would like for said group to include women)?
You don't see anything like this in female-dominated professions.
But only because we're too insular to notice (again, a social skills issue).
