Earlier quoted context omitted.
Most of the time I see downvotes with no replies it means the person generally disagrees. I upvoted you by the way :)
I think sites would benefit from having more rich voting options, for example: agree but weak-argument, disagree but well-stated, changed my view, etc. Would yield some more interesting ways to sort and rank comments.
Yeah, I think that would work. Especially if 'disagree' is a neutral reaction rather than a negative one, so downvoting for disagreement stops being a thing.
