I was thinking of quite a few people, Gareth. I see people trading verbal punches, and I can't say I'm too interested who started it. It takes both of them to keep it going.

In the big world when people are in a fight, there's a sense in which they are trapped into continuing it to a finish of some kind. But that just doesn't apply on the net. It has to be that people only keep making personal attacks and counter attacks because they enjoy it. Which is OK when it's in play, but gets ugly when it's for real.
