Is there also a reverse issue, where posts that should reach the front-page are downvoted or prevented from reaching it for some reason? I.e. how many posts are there that fit with what HN is for and are popular on similar forums online (such as /r/programming), but still do not reach the front page?

A lot of posts. The overwhelming reason is simple neglect. We've been working on this problem for a while. If you're curious about what we're doing, see the links at https://news.ycombinator.com/item?id=9333611 and in my reply. They're a bit out of date now, but the intentions remain the same.

Right, neglect is an issue, since most people don't check the new page and links quickly fall off it.

I wonder if there might also be a more nefarious problem where say YC alumni down-vote competitors?
