I just wrapped up The Substance of Style. My positive opinion thereof stands. What struck me though, is that the notes I was looking for were indeed there. At the end, with no reference to them whatsoever in the text.
It seems strange to me that a book explaining, and in no small way, advocating style, would be presented thusly. I obviously didn't care for the way the notes were presented, and I think that from a stylistic perspective, footnotes and in-text references fare better than notes presented at the end of a book, with no prior reference.
That in itself, is an instance of "not in my back yard... and not in yours either", an attitude that Postrel addresses, in detail, in the book.
