One weekend five years ago my wife and I were invited to dinner by some friends in north London. Let's call them Sam and Nadia. Nadia is originally from Bulgaria.
On our way home afterwards, I happened to look at my smartphone. There, blazoned across the screen, was a weather forecast for Sofia. Why, for heaven's sake? I could only conclude that Google hadn't merely tracked my whereabouts, but in some sense "knew" the people I was visiting had Bulgarian connections.
