I took a very convoluted journey across London this afternoon, heading for the offices of LBi, where the IAB social media forum was being held. This involved getting on the District Line, then the Picadilly Line, over to the Central Line, then BACK on to the District Line (turns out I had my stations confused) and finally on to the East London overground line. During my journey I came across this sign, which I thought was a pretty nice oxymoron… It confused me, anyway!
