I'll vote for no list needed.
To be honest, I belong to about half a dozen list-servs and I quit getting messages from all of them after a while because they just turned into ... message boards. So I check them now and then to mine them for data, but that's about it.
If we had a project that was being worked on, that would be one thing. The only list-serv I'm actively receiving emails from is my group's internal one. I'll join a Grim Tales project task force, though. GT2.0, magic systems, etc. Something with few emails with very specific purpose that SHOULDN'T be public.
