It's what the fashionable revolutionaries are doing

My favorite paragraph from this NOLAdef account of #Occupy Duncan Plaza

In this pre-meeting facilitators decided that the human microphone method should be used. In New York City amplifiers are banned in public parks. The human microphone method is a practical way of amplifying sound without electricity. The speaker says three to four words at a time, and then those who can hear the speaker repeat the words. It’s easy to see how this can be beneficial with larger crowds, but there were only two hundred people present, and the facilitators had a loudspeaker.
