I am currently in an auditorium at MIT waiting to hear Jack Welch. I have been here since 10:40; the talk starts at noon. It's 11:05 now, and there are already about thirty people in the room, with a steady stream coming in.
I really think that if someone said, "I'm sorry. Jack Welch will not be able to make it today. Instead we will have Tom Brady and Curt Schilling" over half of them would groan and leave. (Not me. I'd move up until I was in reach of giving Tom Brady my phone number....)
