Idea #11: Location based apps

One of the worst things about the current field of location based apps is that you have to go to them. 4square, facebook, everything is in its own sandbox. What if instead, locations could tell you which apps were up. For example, as you walk through a mall, each stores app blinks in and out as you pass it by. Any apps you have installed, such as 4square tell you if there is anything special for that location. The locations could be marked by cell triangulation, GPS, NFC, low power radio, etc. The trick is to have mobile devices pick up location instantly (no QR code fail or taking pics). I think this would be the real power of a location based service rather than advertising. Money would be made by events and some advertising. Anything annoying could be filtered out easily (location spam).
