ETA: Comments on this post will be heavily moderated. My goal in having a comments box on this post, as with all posts, is to have informative comments. I would hope that most of the comments are educational in the sense that I or other readers can learn from them, much as I would expect to learn from a letter to the editor of a publication like Scientific American or a journal.
