Thanks, Panda.
Names matter.
I'm unsure how "Disagree" could be used as a textual brickbat like "Jeers", especially since even a cursory glance at our posts suggests jeering is not contained by the Cheers/Jeers buttons. I suspect the history of usage here is little comfort to a newcomer who finds herself confronted by a dozen jeers.
A jeer is a jeer. Despite the historicity, I'm at a loss to understand why a forum for serious discussion wants to encourage jeering: most of our moderation efforts are directed at containing that counterproductive activity.
Part of civility is saying "I disagree" when what you are thinking is "You stupid ass."
Civility and courtesy create a better experience for all, and, I think, a superior outcome for discussion.
But I don't expect any changes, so I'll just stick with my cheers-only policy.
Cheers, mate!
