ping lists start small...then they grow.
Heh... I'm in no rush... I've got, hmm, three lists, having inherited the GGG list, which is pretty good sized (adding together the indiv list with the weekly digest ping), and which has the great virtue of having been started, handled, and supported by some of the best folks one could ever hope to find on the 'net.
I've started a few different 'blogs here on FR, mostly to keep track of certain subjects with pointers to related topics. I've got a "stop Hillary" 'blog, this one, a cold fusion 'blog (which isn't going to derive a ping list, because I don't have that much interest), hmm, three or four others.
FR is like the crackling fire in the hearth on a dark night.
