Just bought a non-MIT student ticket ($200) for MIT Sloan Sports Analytics Conference 2015.

Anybody else going? Tickets literally just went up for sale. They sell out early each year, so grab yours now!
UPDATE 1: Early Bird general admission tickets (non-student) sold out in considerably less than 10 minutes.
UPDATE 2 (11/5/14): Student tickets seem to be sold out.
