It’s funny, true, and in the right community.

That's never stopped anybody before.

Seriously, more than once I've posted something completely benign, innocuous, and appropriate in a niche community that gets maybe one post a month, and that post receives a score of -10 or something. I don't understand it, but if you want niche communities to thrive, you have to quit caring about downvotes.

Personally, I think that they should only have upvotes, because downvotes are a negative experience for users, and they're too easy to game. You can have bots, sock puppets, you name it. And having a post with a negative score tells you nothing about why it has a negative score. Was it offensive? Who knows?
