By the way I think that this downvote button is really a bad feature that brings negativity.

Don't like a post? Just ignore and don't upvote it!

I always liked Reddit's intended approach: downvote comments that don't add to the conversation.

Sadly, votes are too easily mapped to agree/disagree or truth/falsehood - see the "1,800 karma" comment below as a key example, where it furthers the conversation but is downvoted "because they are incorrect".

HN agrees, and so doesn't have downvoting for posts, only comments. (Posts can be flagged, which is different.)
