i was surprised to see him list frequent flier miles with supermarket discount cards (since i do sign up for the former, but not the latter). i think he's largely right (ie i am inconsistent), but there is also a difference between the two: miles allow airlines to bribe the flier when the flight is paid for by their employer. i think that makes frequent flier miles pay significantly more (and for significantly less information, imho).
