As if by divine intervention, Scott Bolinder, the publisher of The Purpose-Driven Life, told the New Yorker's Malcolm Gladwell that "being able to launch that book with eleven hundred churches, right from the get-go" "became the tipping point." Gladwell is, of course, the author of The Tipping Point, so the quote fit in quite nicely in his profile of Rick Warren, author of The Purpose-Driven Life. Perhaps the repeating of Gladwell's pet phrase back to him represents the tipping point of "tipping point"'s mainstreaming. Poor Tom Friedman, for all his flogging of the idea that the world is flat, hasn't gotten anyone to repeat it back to him. (A suggestion for a little selective quoting in Friedman's next column: "As even Gelflog has noted, the world is flat.")
