A very interesting blog on next applications for iPhone I had been a proponent of social tagging tagging not only as a commentary but also as a marker of history. Have been associated with social tagging projects with UCLA for a couple of years, after participating in the Urban Sensing Summit. We had some ideas even doing social tagging at the Olympics ! I agree with Alex that the time has come for collaborative apps at the phone level and the iPhone as a platform can make it happen !
