Right. Some "Blam" threads tie into evolution, if they're about continental drift or something. Otherwise, even if I find a thread interesting to me personally, I don't ping the evo list. The science subset of the evo list is usually for cosmology, relativity, or maybe other physics topics. At least that's the kind of thread upon which the list was built. There are "mars" threads and "space" threads maintained by others, and I don't want to duplicate those. I try to keep my ping lists narrowly focused, so I don't become a promiscuous pinger.
Thanks. I usually abandon a thread when the crevos show up.
That is the problem with the rights, farm, environemt list I use. Because property rights are so tied into the environmental movement and agriculture I included all three for my list but the number of posts and pings was getting to be too much as you have seen in my freepmail. I have had to cut back and be a little more discriminating.
