I don't think it's possible to build a system without human intervention that keeps the bad content out and promotes interesting discussions.
I disagree. IMHO it can be accomplished with the correct structure. The problem you identify is that subreddits are shared spaces, and the primary signal that they rely on is the sum of all users. As subreddits grow, the signal becomes worse. Weighting the votes of users could help, but then you are implementing a moderator bias, and not being honest with people about their input would almost certainly lead to blowback.
One of our goals with http://hubski.com was to avoid this problem. Our approach was to avoid shared pages, and instead allow users to build a feed by following other users or tags. That way we don't have the problem of 'keeping bad content out' to begin with. Instead of voting a story up a page, users share the post with those users that follow them. Posts propagate from user to user. Therefore content cannot be 'buried' by competing with other posts in a shared space. Of course, we are not anywhere near the size of Reddit, but it has been working well so far for us. Each user is their own moderator.
Thanks. Feel free to send feedback along after you kick the tires. It's always useful to get a fresh perspective. We always consider Hubski to be a work in progress.
