I just want to chime in and say that I've been thinking about and researching solutions to this for years. Only recently have I been pushed towards creating a real product that does solve this problem (due to enough people liking the idea at a Lean Startup Machine competition for us to win). The idea is relatively simple...we prioritize content by segregating people into dynamic communities consisting of users who are highly similar behaviorally. The goal is to create a million little hacker newses behind the scenes. Practical implementation is more of a nightmare, but at this point we're in limited beta and you can sign up to receive an invite at http://foldr.co http://foldr.co (just go to launch in the upper right and put in your email for the invite). This project is my personal crusade, primarily because I have watched so many great communities die. I can't say for sure whether or not the solution will ultimately work, but it won't do any good if nobody tries.
