Look here for a very, very comprehensive listing of 2.0 sites. There isn’t a category for coaching, spirituality, personal development, etc. but sites like Inpowr are listed. An excellent place to find what you have missed!
UPDATE: I’ve been around Web2.0 for a while now and I rely on information coming to me. On looking at this site again, it was a surprise to find many applications I hadn’t seen before and that some favorites had gone out of business.
