Social Graph or Social Network?

It's all semantics. Now that Tim Berners-Lee, is commenting on this new hype, let's keep it simple. If I tell to my friends that they are in my "social graph" they would not get what I am talking. But if I say that they are in my social "network", they would understand that easily. So for time being I would stick using the "network" and FOAF for simplicity.
