Despite owning some of his books, I can't say that I am a fan of Gladwell's writing style. But his Revisionist History podcast (revisionisthistory.com) is, by far, one of my favourite things to listen to and I highly recommend to give it a shot.
I also enjoyed Saigon 1965 (S01E02) and the one about McDonald's french fries but more importantly the beginning of the war on fat in America (S02E09).
He unearths some good perspectives in the podcast and it doesn't have the pop-sci feel that his books do that get my BS detector going.
