I had lunch with three of the four authors of the Cluetrain Manifesto.    I'd met Doc Searls before, but not David Weinberger or Chris Locke.  The Palladium d00d from Microsoft was there as well (didn't catch his name), so the conversation revolved around digital rights management to some extent.  I've read the book (Cluetrain) and while I can't say I agree with everything thats in it, I found it thought provoking and would recommend it to anyone who wants to understand how connectedness changes business.  At some point, I think it would be interesting to research the same question with respect to government.
