Excellent work, and much needed too. Besides evolution, I also maintain a science list, which is mostly used for physics, especially cosmology issues, and various other topics (SETI, etc.) if they interest me. It's a subset of, and thus not really separate from, the evolution list. What keeps them all together is my personal choice in threads. But over a couple hundred freepers seem willing to go along.
My science list shouldn't be confused with the space ping list maintained by another freeper, but we sometimes overlap on the same threads. Similarly I'm often pinged to Archaeology/Anthropology threads, but I'm usually not there. The confusion and overlapping is probably inevitable.
Blam, FairOpinion, StayAt HomeMother, and Ernest_at_the_Beach are all co-managers of GGG, and they and other members of the list contribute the bulk of the topics. Any topic from me is generally also found on my links page, with the notation "(I started it)", but some of those are political or otherwise not a GGG topic. Thanks to all who help.
