David Weinberger did a talk at Google about Everything is Miscellaneous. It borrowed a bit from the keynote I heard last year at KMWorld – and is just as exciting. I highly recommend that you watch it if you have some time to devote.
David is a great speaker and just draws you into his world and gets you all excited – or at least that’s what he does for me. I listen to him talking about these things that obviously excite him and I want to learn more and share the excitement.
