I know that we can't make people be nice, but I can't help feeling that if the culture changed a bit there would be positive feedback all along the line. Not a vicious circle, but I dunno, some happier name. New editors arrive and find long-established members behaving in a less than polite manner. And getting away with it. Naturally they take this as par for the course and retaliate in kind. Or less than kind, if you smoke my drift. Now, my feeling is that the overwhelming majority of Wikipedians are polite, friendly, hard-working people, and there are many here I enjoy working with. But there's a few... And yes, you can probably include me amongst that few. When I find someone sinking the boot into me, I tend to apply a bit of needling in return. Peter (Skyring)
