Pat,
I hope that you discuss the advertising side with those further up the totem pole as it would be sad for your work not to be readily available to those on PPRuNe who might like to purchase the information.
Unfortunately, PPRuNe costs a truckload of money to run and Danny et al provide a great service to the aviating community generally at no cost to those who use it.
The "downside" is that those who can benefit commercially from it really need to make some contribution to what is a very directed marketing avenue for aviation things.
Personally, I hope that you continue to play in the sandpit as your accumulated knowledge represents a very useful resource for the readership.
On the "why doesn't Boeing put this or that in their books" question
(a) I can't speak for Boeing but consider

(ii) sufficiently general to avoid having to tailor the documentation set for every individual aircraft and operator, and
(c) they have to have a consideration to the possibilities for Regulator certificate action and/or litigation
