I also agree with a lot of what Dave has said.
The GBs have on occasion tempted me out of my comfort zone, and I do like them. On the other hand I can be a very slow builder and on occasion because of work I can go 3 or 4 weeks without getting to my bench.
I also have been guilty in the past of saying I will join a GB and then having to drop out due to other commitments. I am desperately trying to finish a Fairy Fulmar at the moment so I can start the Kurt Tank GB.
I think that is the root of the issue, providing enough topics to interest people in joining a build, but not so many that too any are left with no takers.
