Web 2.0's democratisation of media produces a wealth of new perspectives. Those formerly excluded from the public sphere have the chance to make their voices heard. But this wave of participation is as important for busines as it is for the newly included. Mute's Web 2.0 special uncovers the work in social networking and the centralisation of the means of sharing. Features texts by Giorgio Agostoni, Olga Goriunova, Dmytri Kleiner & Brian Wyrick and Angela Mitropoulos. With additional articles by Brian Ashton, John Barker, Paul Helliwell and Merijn Oudenampsen.
