Both approaches have value. I value Facebook's closed nature, as it gives me a place to communicate with close friends and family. I live across the country from most of my family, but I see their photos and keep up with them all the time, it's great. Also, on G+, I have to put people in a circle if I want to broadcast to them (and not to the entire world), right? So I'm still following people I might not want to be following using the asymmetric approach. The stuff I post on my blog is a totally different kind of communication, and I'm happy to do it outside the context of social networking.
