I've thought about doing something similar with the metadata of posted urls but obviously that might be ridiculously easy to game.
Unfortunately it's invite only.. To each their own.
People keep complaining as the site grows that the content no longer reflects their particular views. To me, there are two possible solutions to this, or three, if you count "just ignore it": enforcing a more narrow definition of what can and can't be posted, or else smarter filtering of content.
Just because it happens to be making money now doesn't necessarily mean some aspect of the design isn't keeping them from making even more money.

But, let me ask you something: Would HN become what it has become without a strict dictator?The morphology of the site must in some way shape the interaction between users, and by extension the way they perceive the community as a whole. Different decisions both in policy and in design would lead to at least subtle differences in what Hacker News is.
But i'm not confident that adding a feature to organize the posts a bit more necessarily undermines something fundamental about the nature of HN. Nor do I think the only thing keeping this place civil is pg keeping his thumb on the ban button.
