No, a lack of upvote on a comment usually means the comment was wrong according to someone and it spawned an argument. I definitely don't want those cases ranked higher than good discussions where all commenters are receiving votes. Similarly, an article that someone spends 10 minutes reading and then doesn't upvote (or comments without upvote) means it was probably a massive waste of time.
