I was in chat today, and the other guy says
"As I see it, users canupvote/downvote answers in the way they think appropriate to sort the answers to their opinion. In this case, I saw xyz's answer too down for its value, and more related to the question than yours."
Is this good practice? I don't think it is. I feel answers should be valued for their own merit, not what the other answers are like.
I take downvotes seriously, and for me they say it's a really bad answer.
