Slashdot's ratings and meta-ratings back in the day, where you rated something as Insightful/Informative etc, and then every so often you were asked to review other user's ratings so their future ratings could be weighted ... technically interesting but really cumbersome. I like HN's choice not to display ratings on other people's posts, and I like the simple UI. I think it's better with up and down votes than without... I don't think we're going to find a perfect scheme but that doesn't mean we should abandon the imperfect ones.
