I was thinking to have a feature to filter out newbie posts (aka from people with low reputations). They would be placed in a different pool with lower reputations until they prove themselves. Maybe specially assigned moderators will be the judge of doing this. Whenever I'm looking for interesting articles I first have to look through tons of uninteresting or uninspired content of people that either don't know how to make their stuff interesting or just post trash hoping to make a quick buck. So in short, reputation based pools would be good.
