Here is a good example of an application of Bernie Hogan’s Facebook edgelist extractor. Alan Shussman used it on his own Facebook account and generated the following image:
Alan used the NetworkX tool and python to build this image of his sub-groups in Facebook.
It does work nicely to highlight the life-stage clusters of relationships that mostly stay inward focused, each school or work experience is a set of relationships that mostly link to themselves.
I will post a version of my own network shortly, but it is more dense and interconnected than this image. It would be interesting to contrast several egonetworks to see how differently different people network with one another.
