I think I’ve settled on the latter. Disagreement is maybe best communicated by the absence of an upvote? And downvotes work best when they signal something that is just off base, and while not reportable, is not appreciated at a broad cultural level.
I think someone else mentioned the same here, but as I’ve browsed down the opinions, I wonder if it’s good for different communities to have their own subculture on what votes mean.
For sure, outsiders dropping by might vote ‘counter-culturally’ and unhelpfully, but you can get a general sense of understanding in a community.
For r/all-alike stuff I’m sure things are different.
