The service is essentially a form of Augmented Reality, augmenting physical locations with geotagged web content. The potential for fun and value here is huge and I’ve long wondered why no one had built an app like this.
Still in the testing phase but the potential here is awesome. Imagine traveling and wonder what something was, or if the food was any good there. Pull out your phone and pull up what is on the web about where you are standing. Huge potential here.
