Upvotes help get great comments near the top of the page. It is not perfect but better than simply being in time order and a great comment getting lost in the middle. Downvotes mean you can get bad comments towards the bottom. So that is good too. But if you people reply instead of downvote, then trolls know they will get lots of free troll food when they comment, so that will encourage them to post more.
