Ah, I suppose I can be a bit more specific about my process.

Posts: upvote if I care/liked it, downvote if I don’t care about the post so I will hopefully see more of what I care about, and less of what I could careless about.

Comments: upvote those that add value, and really only downvote those that specifically subtract value (mostly when people are being jerks)

Parallel to the join-lemmy.org documentation (see below) I upvote what I want to see more of, and downvote what I want to see less of.

“You can upvote posts that you like so that more users will see them. Or downvote posts so that they are less likely to be seen.” ~ https://join-lemmy.org/docs/users/03-votes-and-ranking.html
