Geoffrey Pullum, the co-creator of the language website Language Log, sums up his site's popularity this way: "A: We like to have fun. B: We enjoy writing. And C: We're linguists." Over 40,000 people a week visit for a smart, witty, wry -- and, yes, fun -- take on how we use this English language of ours. Now Geoffrey and his collaborator Mark Liberman, both linguistics professors, have captured the flavor of their website in a new book called Far from the Madding Gerund and Other Dispatches from Language Log. We called Geoffrey to talk about his work.
