Sure, such feedback is rare, it does require significant feedback in both directions, it doesn't work with single upvote/downvote swings.

It's also very obvious when you've said something that annoys one individual as you can get a string of downvotes in quick succession across multiple comments. Such feedback is easy to spot and see as childish, so I enjoy it for what it is instead.

That said, I much prefer comments, even those that disagree with me.
