This document discusses the growth of location-based services and spatial networking. It notes that by 2015, around 2 billion smartphones will have been purchased in the previous 3 years, enabling companies to know people's locations. Spatial networking allows real-time communication and collaboration with others nearby, even if unknown. Maintaining a personal location history will become common, and this can reveal shared interests between individuals and psychographic profiles of places. Privacy is a core concern of spatial networking.
