In theory I ought to be able to compile such a summary from stuff I've written before. In practice, in the time it takes to find the right excerpts, then edit them so they fit together and fit the audience, I might as well start from scratch. Plus there is the possibility that, in forcing yourself to improvise, you come up with a better way of expressing an idea that has previously eluded concise articulation.
So that's what I did. I'm not sure how successful it was — feel free to tell me in the comments. Since I'm speaking to an audience primarily concerned with policy and the 'creative economy', I thought I'd emphasise the anarchic nature of discovery and Web 2.0 to see how that grabs people. My summary is below (click the "continue reading" link if you're reading this on the home page).
Meanwhile a quick mention that I apparently can invite two guests for next week's MusicTank discussion — featuring Tom Robinson, Andrew Keen, Paul Brown from Pandora, me and others — for free. If you'd like to be my guest (it's in London), please add a comment or get in touch
