"My aim is for the book to cover most of the xml-ish syndication standards, but to concentrate on RSS0.9x and RSS1.0. ... Meanwhile, and over the next few months, I would very much appreciate hearing from anyone with ideas/issues/bugbears/preoccupations/fetishes or any other interest whatsoever in RSS. Are there any issues you feel need strong wording? Any common errors you'd like to see highlighted? Any interesting uses of RSS that you'd like to see in such a book? Any future developments that you would like to get into a book coming out in 6 months or so?"
