>I read it (would it not be strange to recommend a book one has not actually read? :). It is very interesting, thought provoking, and well written about how social phenomenon can transition radically with even just small input causes.

It is a very interesting book. I read it 5 years ago or so, when it was relatively new. Haven't yet read his follow-up book, Blink, about how quickly we make decisions about things.
