As one issue this morning we came across issues related to privacy. In particular it seems that social network analysis based on behavior in the real world (e.g. the reality mining project [1]) is creating serious interest beyond the technology people. Beyond measuring the frequency of encounters qualifying the way people interact (dominance, emotion, …) will reveal even more about social networks… 

In our discussion I made a reference to a book: “The Transparent Society” by David Brin. Even Though it is now nearly 10 years since it was first published I still think it is an interesting starting point for a privacy discussion.
