This July, a new mobile app called SceneTap will further augment the hook-up scene. The app is linked to cameras in bars which count the number of patrons and based on facial features determine the average age and the male-to-female ratio. Of course, the decision to go to a particular bar (and not to go to another) effectively alters the dataset. We therefore make decisions about where to go based upon technologically transmitted data about physical bodies. The presence of our own physical bodies then become data to be recorded, transmitted, and factored into the social plans of others.
