The New York Times announced on Monday that Arthur Brisbane, a longtime journalist, will become its new public editor. Brisbane is the fourth public editor appointed by the Times. He succeeds Clark Hoyt. The public editor works outside of the reporting and editing structure of the newspaper and receives and answers questions or comments from readers and the public, principally about articles published in the paper. Daily Finance: The public editor of The New York Times is meant to be the so-called reader’s representative — the official at the paper whose sole job is “to serve as an advocate for the interests of readers,” in the words of executive editor Bill Keller. But Times readers — and Times employees, for that matter — come in every combination of sex, race and religion, whereas its public editors to date have only come in one flavor: white, middle-aged men.
