Since the invention of the smart phone, I’ve noticed a growing trend in location based content. We’ve seen it in the raise of Foursquare, Gowalla and thousands of geolocation based APIs for both web and mobile. But my question is does anyone actually care where you are at any given moment? Maybe your mother does. She’s always been a bit of a worrier, right? I know mine was growing up. Is that really why these systems keep popping up?
