"There are cries from the heart (e.g The Open Social Web Bill of Rights) for my friendship, that relationship to another person, to transcend documents and sites. There is a "Social Network Portability" community. Its not the Social Network Sites that are interesting -- it is the Social Network itself. The Social Graph. The way I am connected, not the way my Web pages are connected.

We can use the word Graph, now, to distinguish from Web."
