Seriously, people (and you know who you are) - quit giving totally normal posts 1s and 2s. This is an abuse of the system.
My thinking has come around now, and I actually think the only rating ought to be for "troll". I don't think there's a need for other sorts of ratings. One of Kos's main reasons for moving to Scoop was to permit better self-policing. I don't think that having a way of giving posts high ratings is necessarily part of a self-policing system.
