The tournament was edited by Matt Bollinger, with subject help from Dennis Loo, Sriram Pendyala, Sinan Ulusoy, and Libo Zeng (science), and from Kevin Koai (music). In addition to the submitted packets, the tournament used writing by Matt Jackson, Sarah Angelo, Tommy Casalaspi, Isaac Hirsch, Shan Kothari, Aidan Mehigan, Max Schindler, and Lloyd Sy.
When it became clear that more than the standard 17 teams were trying to sign up for the tournament, Bollinger inaugurated a policy of opening spots for the first 17 teams to submit packets , rather than the traditional method of accepting the first 17 teams to sign up. Some people argued about this on forums.
Island of Misfit Quizbowlers (Doug Graebner, Eric Mukherjee, Marshall Steinbaum, and Matt Weiner) won their first ten rounds to lead the tournament, before going 3-3 and ending in a four-way tie for second place.
