I'd love to see a system where where you could inject nuance into upvotes or downvotes. Say, one set of arrows for agree or disagree with the conclusions, and a separate set of arrows for whether the comment was respectfully or rudely written, and maybe even another set arrows for arguments that are cogent versus poorly thought out. I usually make an effort to upvote comments that I thought were particularly well written even if I disagree with them. But we all have our biases, and I recognize that, as with most people, I'm likelier to upvote a comment that I agree with even if it was poorly reasoned. It would be great to be able to rate comments "+1 informative, but -1 author is being a jerk". Or "-1 I disagree, but +1 polite and respectful". I'm not sure how well it would work in practice. Getting the UI right could be a challenge. Netflix used to let you rate content from 1-5 stars, but they later changed it to just thumbs up/thumbs down. The same pressure that led Netflix do dumb down their system might apply here.
