I'm a white guy from Brooklyn who's been successful in tech -- I'm not running this organization, I'm just doing a crowdtilt fundraiser for it.
But, at the same time, there is a significant problem with the way that people have been trying to address the issue of diversity in general, because it doesn't seem like any progress is being made.
There is a lot of prejudice in the world, and it can be overt as in the case of someone specifically ignoring resumes from people not matching their sex or race. And it can be subversive, such as people subconsciously paying more attention to people more like themselves than people less like themselves.
I personally believe it's this latter form that is the reason that lack of diversity continues to be an issue. There is not a single aspect of our American culture in which we do not compartmentalize people. We still have sitcoms built on the tropes of housework-inept dads and shopaholic moms. We still have separate boys' and girls' happy meal toys. And because of that, I don't think it's surprising that tackling diversity in one of the leaf-node areas has largely failed.
