So we've seen how the 3WM lifeline works and the sort of people that are being chosen. So far, it's been 2 Millionaires (Nancy Christy; John Carpenter), doctors, editors, librarians, etc. So, assuming that there are no repeats in the groups, who else do you think will lurk in the new DIE-mension?
My guesses:
Will Shortz, NY Times Crossword Puzzle Editor
Kevin Olmstead, won some money on some show a few years back ;-)
Ed Toutant, won some money on the same show as Olmstead
An editor from World Book or Encarta or something like that (not Brittanica or the fancier encyclopediae)
