Qualitative changes in privacy induced by quantitative changes in social-communications network topology

How do we form opinions and make judgements of other people?

Can we understand this process in terms of the flow of information through a network/graph?

Can we use this model to understand the impact of changes in the network? (Both structural/topological changes in connectivity and quantitative changes to flow along existing graph edges).

Can we use this approach to predict what will happen as our privacy is increasingly eroded by technology?

I.e.: Do we see some relationship between the structure of a social/communication graph and the notion of "privacy". (Temporal aspects might also be important?)

If the graph changes, does the quality of "privacy" change in different ways, and how does that impact the way that we make judgements about other people, and the way that other people make judgements about us.

What does that mean for the nature of society going forwards; particularly as developments in personal digital technologies mean that increasing amounts of highly intimate, personal information are captured, stored and disseminated in an increasingly uncontrolled, (albeit sparsely distributed) manner.

The sparsity of the distribution might be important - in terms of the creation of novel/disruptive power/influence networks.
