How about these variation buttons?
I don't quite agree or don't agree at all, but you have a tendency to rate the same stuff or we happen to get along well, so I will give it an agree.
I agree with 57% of this, but I actually have a real life headache and it's easier to just click agree.
I don't agree and because of my fantastic memory you gave Britney Spears and Church's Chicken a 1 back in August of '06, I will never agree with you again.
I don't agree because it is too hard to deal with the thought right now, or it isn't funny and I don't understand it, so therefore it's a disagree.
