When I don't have a lot of time or am skimming the thread, I use the rating system to determine whether or not I'm going to read a post. If I see five likes, I'll read it. If I see a couple informatives, I'll read it. If I see five dislikes, I'll read it to see the likely horrible take/trolling attempt. If we're going to keep dumping off more ratings like we did to that rainbow and the bad spelling ones, I say we remove them all except the like just to save time. I'm not in favor of bumping the two off, but if we do, might as well get rid of them all except one like it was when the "Thanks" button existed.
