It would be interesting to come up with a way to vote on specific portions of a cmoment. Often when I comment, i'm putting forth many different ideas in one comment box. I don't make 5 comments to put forth 5 different ideas. But because someone disagrees with one of the parts of my comment, the whole thing is downvoted. (And I sometimes have extreme, negative and unpopular opinions, so my average is pretty crummy ;) I would like to see a way for people to show what specifically caused them to downvote; maybe that's categories, maybe voting per-line or per-paragraph, or highlighting and then downvoting?
