What should I use it for?
In case of posts - should I downvote things that I don’t agree with? Or things that I don’t want to see in my feed (posts with low amount of votes fell more to the bottom)? Or things that I consider harmful/stupid/younameit?
In case of comments - should I downvote something that I don’t agree with? When should I use this button in case of comments. Or maybe I should not - cause what’s the point, actually?
Though the downvote is also a tool for brigading. If a systems uses the downvote button for the “opposite” of the upvote button, it’s the same thing just negative/reverse. You can use either one for brigading.
