Slashdot's moderation system (in theory) is excellent. It is more than a + / - button so I don't see it working in a faster-paced environment like facebook comments. I think the happy, sad, angry, and heart emoji-rating system they use now is probably already maxing out the amount of time a user will spend on rating something.
