To me the best thing, the really exceptionally cool thing about this thread is
that it exists at all. Where else can highly trained people exchange viewpoints
in this manner? Before the advent of newsgroups and the Internet in general,
such discourse between individuals would have been very unlikely, maybe limited
to two or three people in some chance encounter.

I have learned a lot reading this post, and I suspect others have too.
