Facebook.com, Apple, Foursquare.com, twitter.com etc all all keen to track your location the moment you use the app from your mobile device. More and more will follow and eventually every app will be trying to get your (x,y at specific time). This is extremely powerful information and will be used in more than one ways by companies. Need I elaborate that? Some other day..
How many LBS apps or apps that use "location" exist in India? I will try and find out. If you know of few interesting ones, please let me know.
