I like this idea. I think the clearest way to do this would be to have an Agree and Disagree link, which led you to a page with a reply textbox and a confirm button. If you wrote a reply, it would post it as a reply; otherwise, it could just count it as an agree/disagree thing, like facebook does it. (Then, next to the first line of each post, it could say "5 Agree; 2 Disagree" or something like that.) That way, agreement/disagreement and good/bad are separated, and displayed nicely.
