Glad to read this. I thought I might be the only one picking up on the irony here. I mean, come on. He JUST read about D-K, then demonstrates it in action.
I agree, although as I said to another commenter, I'm more bothered by assuming others to be incompetent even though they are, than I am by assuming yourself to be competent when you're not. And they're related, but not quite the same?
