The Wealth of Networks: the seminar. We've talked about The Wealth of Networks before. Now Crooked Timber is hosting a web seminar on the book & the ideas in it. How it works: a bunch of smart guys read the book & write essays on it, then post them for anyone to read & comment on. You can read them all together (PDF) or separately with comments: Norms and Networks, A General Theory of Information Politics, Why Do Social Networks Work?, Whose Networks? Whose Wealth?, Mediating the Social Contradiction of the Digital Age, The Dialectic of Technology & the author's response. And now you can join in too!
