I posed this question publicly before (being quite positive about Doc's contributions) and asked if he got paid by FlyerTalk. He said "Of course" but he was leaving the job to spend more time with family.

That hasn't happened (to all our benefit). One of the replies in the other thread suggested Doc was really several people. So let's come clean here Doc: did your flight home get cancelled, do you have 10 coworkers named Doc, are you Randy Peterson in disguise?
