This photo was taken on the roof at White Bear Yard, London EC1, the tech incubator where my partner Noam has his company (Picklive). Philip Vo is an art director from San Francisco, in London for a flying visit and wanting to check out the ad/ tech scene here. So we, um, took him for cheap falafel and told him about Silicon Roundabout. It is hard to tell someone from Silicon Valley about Silicon Roundabout without pretending that it’s all a bit of a joke. Which is awful. Because it isn’t, is it?
