First of all I want to thank all those commenting here. Your thoughts, questions, theories and other comments, even the negative ones, have helped make this blog interesting, meaningful and relevant. You've noted, I hope, that I don't censor posts -- unless they are redundant, irrelevant, inordinately rude or outright spam. Even then I've deleted only a very small number of posts since day one -- as I recall, only maybe six or seven (most of which came from the same redundant source). All viewpoints are welcome here.
