I was on the 2009 ETS committee to come up with questions, along with @
Leviathant and about 4-5 others I can’t remember. It was actually more difficult than you think coming up with interesting questions.
Note that, from what I remember, there were several small groups; one small ETS group and several small NIN.com forum groups, which all submitted narrowed-down questions, which were further narrowed down by the NIN.com forum.
Of course, the NIN.com questions were the dumbest.
Some of the funniest or best questions / answers have been posted here on ETS, randomly, and answered here; e.g. what does lab work mean? Or what is that stuff you’re drinking onstage?
