I'd be very grateful if you took those things on!

Personally, I suspect that one good way for this kind of thing is for
it to be written by a newcomer and then fact-checked by the
veterans...the former group are more familiar with the feeling of not
knowing what the hell is going in.

I think the cookbook is a good format, "problem" "solution" (each of
those a one or two liner) "discussion", "reference", and then
"example" -- ideally ready to compile code, with the relevant bits
highlighted in red, and all the usual boilerplate in black -- that
keeps us honest in our code, and lets the n00bs have the small thrill
of assembling code and seeing the results.
