As HN currently works, you'll know neither who up- nor downvoted you. I overall agree about the downvotes. But I'd personally also really like to see who upvoted, and some of the best reasons of why you don't see your downvoters do not really also apply to upvoters.
So, would you be okay if I saw that you upvoted a comment of mine?
[Edit: Typos and formatting]
Most of us here are for getting balanced perspectives, sharing knowledge on diverse topics and growing smarter/wiser as a community, not just an individual. So no, I do not see any value in finding out who upvoted/downvoted me. Anonymous is the right choice!
