I guess you haven't heard about smileys, Alan. Not that that would have influenced me, of course. :-)

Yes, they are FAQs, and as such should be entries in the NG's FAQ, where answers -- with or without references to the literature -- may be viewed. Constant repetition of "standard" answers to frequent questions is tiresome or, at its worse, a bore. Not to mention a waste of bandwidth.

Yes, I can agree with that -- subject to my other comments.

Hmm, existing literature, perhaps, but with the reservation that the topic cannot be found in the NGs FAQ. Constantly referring to (as yet) unpublished texts is ill-advised; the book may not even be published (for a number of reasons, not least because another author has "beat the gun", making it uneconomical for the publisher to proceed). IMHO (FWIW).
