Our guess, all in, staff, speakers and everyone #defcon was close to 13,000 people. Twitter poll was 16,000 so we have plenty of spares.

My guess was: (2^14)-1 = 16383
For all attendees (humans, speakers, goons, vendors, press, etc.)

DC20 did not grow as much as I expected since Defcon 19.

There was a HUGE jump in people between Defcon 9 and Defcon 10.
