Los Angeles - Radiohead has launched its own social networking site, based from the same W.A.S.T.E. merchandise website that offered its "In Rainbows" album on a pay-what-you-want basis, Pitchfork Media reports. At launch, the W.A.S.T.E. Central site lets users create profiles, see who else is going to shows on the band's current tour, and view and upload photos and videos.
