I'm starting to believe down-voting has gotten more useless and should be removed. Perhaps up-voting is sufficient, but maybe not.

Unfortunately, Facebook demonstrates that only positive feedback tends to cause problems.

I do agree that downvoting (especially on political threads) is not working very well.

I’ve been on HN for years and still can’t downvote.

I believe your "karma" has to be above 500.

Maybe list of downvoters and upvoters should be public
