I've noticed something. You're only supposed to rate 1s or 2s if something is a troll or marginal acceptable. If its something that you think is boneheadedly wrong, though, you arn't supposed to rate at all. 3s and 4s are theoretically rated for cogent, interesting or funny comments, but most of the time a 4 rating boils down to "I agree enthusiastically." Which leads to comments that you might think are boneheaded getting many fours, but of necessity you cannot rate them a one (because that is reserved for 'Troll') or a two (because CW is that being mistaken is not sufficient grounds for a 2).
It seems to me that ratings of 1 being troll-rates is completely unnecessary, for any actual troll is immediately barraged with zeros.
Therefore it seems to me that the scale should be opened up a bit- trolls shifting to zero (where it belongs and actually is), marginal shifting to 1, and some new rating (dumb? wrong? wrong-headed?) being placed at 2.
Relevant to the discussion is that if you move Troll to Zero, none-Trusted Users cannot Troll-rate. I don't think this is so bad, as the vast majority of none-TUs never actually see troll posts as they are jumped on immediately by TUs (who, it is assumed,spend much more time reading and rating than non-TUs. Cheers and Jeers Empire excluded.)
