You really contradict yourself here. Why is it worrying that your cultural diversity isn't representative of the demographics of California and yet it doesn't worry you that women are under represented?

Because we're going to have a discussion on diversity regardless of my personal convictions and I would prefer that we focus on being more inclusive of minorities and spreading "hacker culture" to low income neighborhoods (ie: people for whom the barrier to entry may be as high as simply being unable to afford a computer to code on).
