There’s growing evidence that if you are part of a social network, the structure of the network itself can reveal important information about you, regardless of what you have published yourself. For example, in December we looked at a study of a computer gaming network, which showed that if you have friends who cheat at computer games, you are much more likely to be a cheat yourself or to become a cheat in the near future. In a way, that makes sense. We are much more likely to copy the behaviours of friends than of other people. Today, Kazem Jahanbakhsh and pals at the University of Victoria in Canada add an interesting corollary to this work. These guys have studied the geographical clusters of photos that users upload to Flickr, the popular picture sharing website. The task they set themselves is to determine an individual’s home town looking only at the geotags of photographs they have uploaded.
