Paul Lewis in the Guardian today on the way he and his colleague film-maker Mustafa Khalili used Twitter to cover the riots.
He writes: "The first portal for communicating what we saw was Twitter. It enabled us to deliver real-time reports from the scene, but more importantly enabled other users of Twitter to provide constant feedback and directions to troublespots. While journalists covering previous riots would chase ambulances to find the frontline, we followed what people on social media told us. By the end of the week, I had accumulated 35,000 new Twitter followers."
