Castells: Seeing Networks Everywhere He Looks

A little obligatory reading lately, namely Manuel Castells on the network society.  This is for my ongoing research project on emerging internetworking practices (i.e., what most people misleadingly refer to as ‘the internet’).  Castells I regard as obligatory here insofar as my object of inquiry in many respects overlaps with that on which his impressive body of work is focused.  But in a first pass through some of his most recent suitably-sized (i.e., <50 page) self-summaries of his work, I am struck by the extent to which my method is quite different.  So what are the differences?
