No matter where you go, upvotes and downvotes are still subject to the Lizardman’s Constant. Someone will end up voting in a totally contrary way just to be contrary, or because they didn’t understand, or because they just hit the wrong button. No matter how great your content is, it would be weird and possibly suspicious if it didn’t get some downvotes.
I vote on every post I see. That combined with the “hide read posts” setting means I always see new stuff on the front page.
I upvote any post that I want to see more of in the community it was posted to. Posted game news in a gaming community? You get an upvote, whether or not I actually like or care about that game. I also upvote anything I don’t have any particular reason to downvote. It’s my default vote.
I downvote any post I want to see less of. Clickbait titles or misspellings are an automatic downvote. Off topic posts are always a downvote. And any post that comes off as salty gets downvoted, especially if the post is salty about being downvoted. I just don’t want to see any of that, so I use my vote to discourage it.
