“The explosion of communication technologies has made long-range interactions between individuals increasingly easy. Paradoxically this ‘virtual’ shrinking of the world, through constant access to contacts across the globe, often isolates us from those in our immediate vicinity. However, as mobile phone evolve to break computing free of the desktop and firmly roots itself in daily life, we have an opportunity to mediate, mine, and now even augment our current social reality. We are beginning to see advances in communication technology that will enable face-to-face connections between strangers and make a profound impact on our society.” (MIT Reality Mining)
