I was fortunate to be at this fascinating discussion, but if you missed it and are interested in these topics you can now see the webcast at the above address. Official description below:

On 11 September, NESTA Connect hosted this event about the tools, techniques and foundations that are important for mass collaboration.

Howard Rheingold and Mark Earls, writers who examine and challenge traditional perceptions of mass behaviour change and cooperation, spoke eloquently and passionately about the extent and nature of human co-operation.

Roland Harwood, Head of NESTA Connect, followed these speeches by chairing a lively Q&A session with the authors and invited audience.
