This was all in the context of large teams, larger than the Agile methodology recommends. How much useful stuff do you think a developer can fit in 20 seconds of speech -- which is about all they get if you want to fit a 15-people meeting in a ten-minute timeslot? Once a team grows past a certain size, either you keep the discourse substantial -- and end up with 30-minute meetings -- or you cut everyone short, and end up with ten minutes of smiling and saying the right buzzwords.
