I read recently that, in the future, search engines will be able to reveal people's whereabouts at a given time, simply by the electronic footprints they've left. For now, though, that information is mostly captured voluntarily, making it largely the provenance of blogs. So it is that, if ever asked where screenwriter John August was when he started a play in late 2006, you can boldly answer "Chicago" -- qualified, as he notes for posterity, "technically, Evanston."
