Bloggingheads, home of the "diavlog," is now featuring a discussion that I had with fellow Language Logger John McWhorter about a whole range of linguistic issues, from lexical chunking to pop-Whorfianism to Obama's Indonesian skills to the language of Mad Men. Something for everyone!
[Update, 9/18: The segment of our talk on "Mad Men" has now been excerpted on the New York Times website. Careful viewers will note that the clip ends just before my discussion of the word shithead. Can't slip one past The Gray Lady.]
