One of the odd things about the social graphs for me is that I have multiple distinct social graphs that overlap little if at all. I expect there are many people that want to really be sure they are keeping their work, personal, and family lives separate. For example, my high school friends probably hate my updates about programming and computer topics. And honestly I don't care much about their trip to the river. On the other hand, my more professional friends (who I don't interact with on twitter) could care less that I'm walking the dog but are happy to chat about programming. For that reason I have multiple communities: Facebook, Twitter, Reddit, HN. They each have different social graphs and I discuss different things with each of them. Facebook's is trying to connect to these other sites to connect usernames to Facebook profiles, but I'm not sure I want all that going back to the same place.
