From David Armano's blog, Logic + Emotion
[LATER] Well, first I had nothing to add. Much as I like the graphics and respect the Logic & Emotion blog, now Im not sure that the big ripples have this kind of influence. Mark Earls is right: people are more influenced by their immediate group than we realize. And now, more than ever, every friendship group is a cult, every community has its own common mind that influences everyone in it, far more than the breakfast cereal ad on the TV.
