Is getting into the music business?

Ethan Kaplan, Warner Bros.'s 29-year-old vice president of technology, uses Twitter like his cohorts. Well, almost like his cohorts. He slipped up using Twitter's direct-message feature, and broadcast to the Internet a request to talk to someone in business development at Despite advertising "Shoes, shoes, shoes!" on its website, Zappos has branched out into selling everything from camping axes to computers. Could it be branching out into music, too? It's hard to think why Kaplan would want to talk to Zappos otherwise — unless he's figured out that the music industry doesn't have much of a future, and it's time to find a job at a more promising company.
