I think the problem with what your proposing is that it lets people know what other people think about a node before they vote on it. I think the general concensus has been that this is a bad thing because it might sway votes one way or another. So i think you would have to have an extra voting option one way or the other. Currently, after you vote on a node it shows the number. I think what has been suggested is something where a node would act as if you had voted for it, except the reputation wouldn't change one way or another. Perhaps visual cues would be better than the number, but I don't think we should get them before we have voted on the node, or decided that we're not going to vote on it...
