True colours

Funny thing about the web is that you can get a real feel for what people are like. I mean you can have two really bright, intelligent guys who write about wide ranging subjects and get a really clear sense that one of them is one of the nicest guys on the planet who just likes to chuck ideas around and make it up as he goes along and the other is a cantankerous curmudgeon who tilts at windmills and gets grumpy because the world isn't nice and orderly like he thinks it should be.
