Walter Kirn: Calling Card Pitchman?

You gotta admire a writer like Walter Kirn. One week, he's telling us how we live now in The New York Times Magazine, the next he's sharing his experiences as an outsider at Princeton, the next he's reviewing books for The New York Times Book Review, the next he's explaining fly-over country in TIME, then he's writing copy for an international calling card website. All while waiting for the movie version of his book to come out.
Wait, roll it back: Kirn's writing for an international calling card website? Work's work, right? Besides, the article ("Why Walter Kirn won't be attending the Charles-Camilla nuptials") already ran as a TIME web exclusive, so it didn't cut into his day too much.
But, boy, Kirn is prolific! And these are some pretty good calling rates.
