Oh, I love the marketing word. Marketing's great. It's the tail that the dog should wag. Unfortunately, many get it backwards :)
I think your idea is a good one, i.e. a centralized page for documenting OpenACS sites that goes beyond the simple listing-with-comments form we've got now.
As to when something like that gets down, seems to me we're all pretty busy with OpenACS 4.x at the moment!
One nice thing about openacs 4.x is that the independent module structure allows folks to offer alternative module implementations. So, if your general comments module, once ported to 4.x, provides the same API to client objects as the existing one does then you could supply it as an alternative folks could download into their copy.
