As I said over there, any satisfactory solution would need to be dynamic and collaborative; and PerlMonks' existing features don't facilitate this too well. Probably the best we can do here is our wiki node type, of which we have several extant examples, such as this one. I'm not sure how good the locking is on these; it might become an issue if lots of people are trying to contribute.

Using threads in sections (such as this one) is bound to fail, due both to the non-collaborative nature and the intrinsic obsolescence of ordinary writeup nodes.
