Mobile Social Networks

A recent post on the New Scientist Technology blog highlighted the research of Vassilis Kostakos who has developed a FaceBook application that uses mobile phones and bluetooth to "introduce" you to people you get close to in person. CityWare uses a local bluetooth network that detects phones running the application that are close to each other. The New Scientist post also refers to another application Kostakos is writing that will update you with news about friends that are physically close to you. This work raises the usual privacy concerns outlined in OpenSocial: Pros and Cons and I think illustrates the innovator case of boyd's post.
