Uh, does it not seem logical that if there are fewer black/Hispanic minorities in tech, that there will be fewer blog posts from that perspective?

But just because you don't ever see it discussed on HN doesn't mean that it isn't. Try out the HN search engine:

Here's a discussion last year on the YC blog post that was titled, "YC Open Office Hours for Black and Hispanic Founders"

Because we get flagged down a lot. This thread managed to survive because we started a big twitter stink to try and get it unflagged, and because we had the international women's day hastags to get attention, it managed to make the front page. But even that was a struggle.

Many of us, myself included, fight on behalf of a lot of underrepresented groups on HN as best we can.

I'm sorry if you haven't seen it, but I assure you some people here are trying.

I see it come up pretty regularly. It usually is then followed by racist pablum of one sort or another--so the resistance to racial issues isn't exactly different from the resistance to gender ones.

As others have said here: if you don't see it, that should tell you something. The lesson isn't that minorities don't talk about their own issues.
