JM2CW ... since there are already so many other sites which invite discussion about “any topic you wish to name,” I personally don’t think that PM needs to join them.   To me, PM is what it always has been:   a crusty old site, visually stuck somewhere in the 19th Century, which nevertheless is “the GOTO site on the Internet, for anything related either to the Perl language or to everyday professional uses of it.”   I frankly don’t see value in making it more of a watering-hole.   That will simply make more work for the gods and other moderators.   (Who, by the way, always do an excellent job.)

When people find particularly-relevant URL links, they can simply add comments to existing threads which contain these URLs, or create new threads.   I don’t see PM as being ... or, as needing to be ... a “Wiki” of any sort.   You come here to do one of three things:   to ask a question, to answer one, or to perform a Super Search over the site’s old and truly-vast topical database.

I think that PM needs to continue being what it is:   a place where you can ask any question about Perl (or any of the esoteric ways in which it is being used throughout the planet), and get an authoritative answer ... usually, complete with code samples ... in a matter of minutes or hours.   It is now a very focused group, and I opine that it should stay that way.
