Yesterday I started reading Barabasi's "Linked: The New Science of Networks". It's inspiring, in many ways. It makes me realize how different my life is, compared to most nodes in the social network of human connections. I have many connections, but compared to most people, most of my links are weak. I met so many people in so many places, mostly for very brief periods - i.e. a ride in their car, staying one night at someone's home.
