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?
Not sure about always. Wouldn’t an attention seeking troll posting something controversial enjoy tons of comments instead of downvotes? I guess a protocol is to upvote your favourite dissent instead of commenting?
