Gah! On heels of news that The Atlantic Monthly‘s circulation is the now lowest it’s been since the late 80s comes this: Their absolute A+ ace reporter William Langewiesche is leaving for a job at Vanity Fair. And — maybe even worse — managing editor (and soul of the Atlantic) Cullen Murphy is out, too. His short travelogue this month on Hadrian’s Wall (subscribers only, sadly) is classic Atlantic. In other words: totally unexpected and totally smart.
