In July 2004 an anonymous blogger revealed his identity when he allowed his photograph to be taken at the Democratic National Convention. “Atrios,” the writer of a prominent left-wing blog, Eschaton, turned out to be Duncan Black, an assistant professor of economics at Bryn Mawr College. Black had worried that a trenchant political blog might be perceived as inappropriate for a young academic and also wanted to avoid invasions of his personal and professional life. He went public only when he had quit the academy to join Media Matters, a watchdog organization.
