Our friend Sree Sreenivasan,
on the J-school faculty at Columbia, posts an interesting column on the
Poynter site today on social networking.  Remember, “social networks” is/are not quite the same as Social Network Analysis, but they are close conceptual relatives.  

Sree has linked to some valuable sites we didn't know about, so check out “Social Networking for Journalists” at http://www.poynter.org/column.asp?id=32&aid=91496
