Ask HN: Why/when do you downvote?
I'm back on HN now because I caught this LLM bug and am obsessed with building/open-sourcing stuff with them, and am having fun contributing to the big repos. I have questions for some and answers for others and ultimately I'm netting mountains of daily knowledge and inspiration from this site for which I'm grateful. A lot of the people here have a gift for wording things to make them understandable such that it makes HN like paid-quality content but for free. Yet there are others, who often have extremely high scores/karmas/whatever who are clearly only here to sh*t on people and seem personally smart - and they're apparently being rewarded for it with the point system here.
So the prompt is simple - why do you downvote?
What's worthy of it, beyond spam? What do you get out of it? Does HN benefit from downvotes in a way that flagging does not and cannot address? If you don't downvote, answer why you upvote - I'm really curious about the reward system here, what it means and is all about. Why people like and dislike certain kinds of content here.
