Well... I'm just curious as to if there really is a one-size fits all. I sort of think it depends on where you are in your career. I said "opportunity" because I value the whole experience of going. 1Q84 is an MA student according to the forum, so say for instance that the grad conf was at 1Q84's dream school and they were flying in 1Q84's second "top POI" to be the keynote speaker from his/her second dream school. Would the opportunity to work extra close with a few folks that really matter outweigh the conference "prestige"?
Just curious.
