Just a reminder; no matter how much you rabidly disagree with me or the other commenters, please keep things civil. We got a little close to the edge a couple of times yesterday.
An opinion is an opinion, and worth the pixels it's made of. The right to use the back button is inalienable; use it if it is becoming difficult to keep it friendly in my little salon des commentes.
More substantial post later, and again, thanks for all the fascinating viewpoints!
