Today I found a question that already had an accepted answer. I thought I had a better answer, so I posted my answer anyway. The OP liked my answer and accepted it. I felt very proud of this and thought that I probably earned a badge for this, but I didn't.
Shouldn't there be a badge for this? I consider it something of an accomplishment. Also I think we want to encourage users to give a better answer if they have one even if there is an accepted answer already.
Surely I can't be the only one that thinks this badge is a good idea.
