Heres an idea for a participatory, self-organizing, emergent conference.
It consists of several rounds. In the first round everyone ‘speed-dates’ a
number of randomly chosen other people. They then write down for the people they met suggestions for who they might speed date in the second round. In the second round people the ‘speed-dating’ will be then become less random, and more useful since the ‘dates’ are will be informed by others ideas and intuitions. This can go on for another round or two, with people finding more and more useful people to meet.
After these rounds people write down who they would like to give a talk or lead a session at the conference – by this time they will have met with a significant number of people so can have an idea of who has something interesting to say. The most popular selections then give talks or lead facilitated session for the rest of the conference.
