Well thanks. I too get upset sometimes when a comment I thought was good gets downvoted and I don't know why. Sometimes it's wrong and I only realize that later. Sometimes it's because I'm an asshole. Sometimes it's because other people are assholes. That accounts for (I guess) >90% of comments,a dn keeping an open mind on these possibilities means that I don't get downvoted too often, and that when it does happen I can keep the reasons in perspective and minimize disappointment and hurt feelings.
