[Ubicomp] Revenge of Geography

http://www.economist.com/science/tq/displayStory.cfm?story_id=1620794

Great article in the Economist about location-based services. Talks about uses of location information, geotagging, geoencryption (cool idea, but sounds tough to do well), geomarking ("I'm over here, meet me").

Best quote:

The internet is an open platform, but it lacks ubiquitous wireless coverage and proper positioning technology. Only when openness, ubiquity and GPS-grade positioning are available in the same handset will it be possible to realise the true potential of location-based services.
