dg1: That why I posted the question. Thanks for sharing that experience. Now I have a much better feel for where your viewpoint is coming from.
I take it from your post that (1) moderation really quelched discussion on your list, a bad thing, but also (2) your unmoderated list had problems, else you wouldn't have gone to a moderated one. So where's that happy medium?
Obviously, I would hate it if moderation caused a good list to lose subscribes (other than the inevitable MileageGod69 types.)
