Obviously your frame of reference is for a very limited use case. Three examples of social networking working in the last couple weeks (just from my limited perspective): 1. My mom rediscovering someone she hadn't seen in over 20 years through Facebook. 2. Two musicians chatting on each others' music profiles and figuring out how to collaborate on music online. 3. An engineering student from Africa reaching out to me to comment on his project. Given Garry Tan's work at Posterous, there is some vested interest in the space, but at the same time I don't think his claims are any less valid. I haven't tried Google+ yet, so I don't know if I agree or not.
