At long last I'm reading The Social Life of Information by John Seely Brown and Paul Duguid. It's been out for several years now (since 2000) but is packed with nuggets of good sense and sharp observation on the interactions, and lack of them, between information, knowledge, technology and social fabric. Some of the standouts I highlighted. 'Work is rarely well understood', 'You can't redesign process effectively if you don't understand practice', 'all organizations have to balance routine and improvisation. It was written pre Facebook's huge growth and I wonder whether the authors would have (or will) write on that type of phenomenon. Take a look at John Seely Brown's website. http://www.johnseelybrown.com/
