As I walked past St Paul's Cathedral yesterday I noticed this group of people on the steps, and I wouldn't have stopped if I hadn't seen LESS IS MORE on the placard of the man in red.  As it's one of my favourite principles (which I tend to mis-attribute to the architect Mies van der Rohe rather than the poet Robert Browning who used it 100 years earlier), I tried to listen to what was being said but unfortunately the speaker must have been applying his message to the volume of his voice and I couldn't hear a word he was saying.  I'm not usually one for going with the flow but on this occasion I just had to let it go.
