So, no duel?
I can't believe that I missed this thread! Sweeper, thanks for pointing out my innovative system of coping with negative nods. Was it you who suggested pies in the face at 10 paces? MagicPie, are you challenging me to a duel?
On a serious note, I think the nods are silly because they don't add much value to the conversation. Maybe in a warm, fuzzy convo, it's nice to get thumbs up. But in a discussion of politics, I know that most people here are going to disagree with me. It is not as though I am going to see the thumbs down and rethink my views on that basis. I already know that people disagree with me and would much rather discuss the ideas behind the disagreement.
So to me, the thumbs are the cyber version of a little kid behind me in a movie theatre kicking my chair.
