Considering all of the little goofy BS threads that are not occuring because it all is being parked on the MOAB, you're simply looking at different ways to use the same amount of space.
Or take a different view: MOAB as VIP lounge. Several of the folks who play around at MOAB have have been regular contributors of cash or kind to Mudcat, so it isn't like we're not pulling our own weight. Can the same be said of the lion's share of the visitors or even registered members of Mudcat?
