So Mark Sanford, governor of South Carolina, disappears from the radar screens of the press, his colleagues, his security detail, and everyone else, literally vanishing into - where? In short, Sanford "unwires" himself, in the old-fashioned, pre-Blackberry, pre-email sense, which means no one knows where he is, and no one can find out. In the Manchurian Candidate sense.
But Gov. Sanford is a public figure, now having to confess his sin of infidelity, resigning as Chairman of the Republican Governors Association. He was outed in front of the world because in the Age of Twitter everyone needs to be somewhere, and no one can be nowhere.
Still, before you mark this down simply as one of the unfortunate consequences of fame, consider that our technology now makes each of us more visible, more accessible, and more available than ever before. So when anyone today becomes electronically invisible, inaccessible, or unavailable, expect the anomaly detectors to go off.
