dgolds, Just like you have good experience with moderated lists I have bad ones. I ran a succesful email based mailing list with several hundred subscribers. After a spat of problems we switched to a moderated environment. The level of discourse immediately dropped ... we went from a hundred posts a day -- most good -- to ten or twenty, most bland. Too many people questioned the choice of moderators -- especially since as the owner of the list we chose others as moderators.
So hence I agree with the others here if we are goign to hvae moderation it's going to have to come from someone somewhat detached from the day to day discussion and also with authority from the source -- the owner of the site.
In any case, I think it's obvious some of us want moderation, some don't. A simple test would be to moderate some bboards and not moderate others. Maybe moderate Buzz but not Omni. Or something like that.. and see what happens.
