I would say give it time. The concept of a more clandestine hive thread is still a new idea. Still, I like the idea. I have trouble following the "off-topic" hive threads due to the fact that they go so fast.
We have the second greatest Social Group on EnWorld [in terms of members only, of course. ]
Don't know how CMG has so many members though, but since even I've got an invite, I think they did some sort of spam maybe. Just mean that I've never really done ANYTHING with CMG and yet I've been invited. Weird.
