It depends on the community. I don't downvote on Reddit. The way the voting system is implemented makes it functionally worthless and I don't see the point. I also barely upvote; I upvote comments that I really like/agree with/want to encourage if they're low scoring. Like comments sharing on a PTSD subreddit; I'll upvote if those are low to encourage people to speak/let them know the lurkers support them in email. Can't DV on HN with this account, but back in the Dark Ages, I only downvoted here if the comment was either a.) assuming bad faith/attacking a strawman or b.) pulling in what I recognize as a narrative and not leaving space for it to be questioned. (So Twitter level content). For FB I guess the 'downvote' would be the angry button, but I don't think that's a good comparison, given it is also used for being infuriated on behalf of the comment maker instead of AT them. Though that comparison now makes me want to compare downvoting behavior to car horns: Both are limited communication devices meant to display displeasure with the actions of a random stranger you might never encounter again...
