seriously, this is what pissed me off most about the talk. He talks in detail about the straight up and down in user signups after Time, Newsweek, and TC features, but when he shows the graph of up and to the right, he just said it was "word of mouth" and nothing else, it seemed like he acquired his users through magic. Did users just start to get it? What changed to make it hockey stick growth? It just seemed like it was a lame pitch to work for his company because he has a ping pong table and a room that can be opened with a book.
