In this Screencast I tried to explain what "Distributed Social Networking" is all about. I talk shortly about the building blocks of social networking in general, then point out where the problem is and show you with Noserub how a Distributed Social Network can work.
This screencast doesn't go to much into technical details and has the objective to make people understand quickly, what it's all about.
