From June 2007 until August 2008, he was a staff writer at "The Atlantic Monthly", and his blog was hosted on the magazine's website, "The Atlantic". In July 2008, he announced that he would leave "The Atlantic Monthly" for the Center for American Progress where he wrote for its blog, ThinkProgress, because he missed "the sense of collegiality that comes from working with like-minded colleagues on a shared enterprise" and thought he could "help advance their mission." On November 21, 2011, he left ThinkProgress to work as a business and economics correspondent at Slate's Moneybox.
