Here's an idea: Have karma and voting tied together. Your Karma is basically how much votes you get to give. If someone makes a good post, people upvote it, spending their precious karma. The person made the post, collects the karma and and they can use it to vote other posts. We can limit karma by having new users start off with 0. And they only way they can vote/get karma is to contribute positively with quality articles/posts. Now it works the other way too. Make downvoting take away karma of the OP too, thus making people put more thought into their posts. The downvoting action will cost a vote, so people don't running around downvoting everything without thinking. Basically let Karma/Vote be a resource that can be used to promote positive contribution and dissuade useless contributions. The tricky part is balancing the karma in the whole system. Downvoting siphons votes/karma from the system, we need a way to introduce additional karma/votes into the system. Maybe a monthly replenish method where say everyone gets 10 votes each month. But in order to qualify for the monthly bonus, you must first contribute enough (get the up votes) past a certain threshold (say 100 upvotes to your posts/contributions).
