Eigenvalue/SVD upvoting. Comments and articles are ranked for you according to their ranking with similarly voting/submitting/commenting users. The frontpage (depending on how you set it up) could look like Reddit's, based on the majority of users, but to logged-in users it'd be more refined to their tastes. Perhaps you could look at the site from others' perspectives. Defining the model, computing likenesses and finding the appropriate material could be quite resource intensive if you didn't think long and hard about the implementation. (You'd might also want to avoid up and down arrows, because "like" and "dislike" quickly supplant "good comment" and "bad comment".)

The very first time I saw a site like this, many years ago, that is what I assumed all of the voting was about. I know a lot more now than I did then why resource wise it is the way it is, but I occasionally think about how one might go about doing a more customized version. Superficially at least, it seems to be a good way to put everyone into a community whose size relates to the commonness of their preferences. I think this would occur as long as comments/articles beneath a certain threshold just weren't visible to a particular user. Unfortunately it seems like a lot of calculating to do per hit, but in thinking about it, it doesn't seem to hurt Netflix too badly.

If it's too much complexity to track each user's preferences in terms of every other user's, you could also take a Bayesian filtering approach, similar to junk mail controls, and compute a custom front page based on each individual user's prior upvotes/downvotes. In either case, the function of the voting mechanism will ultimately shift from generating the public front page to generating a custom view for each user. At that point, you could re-purpose the public front page as a selection mechanism to draw in the highest-quality users - perhaps by choosing a cohort of existing users to have public-upvote rights, or even by just applying old-fashioned editorial controls.
