Yelp, the popular review site with its own location-aware iPhone app, can get even more up-close and personal with its users' takes on everything nearby. Download the app and fire it up, then shake your phone three times.
Now you'll see the closest Yelp-reviewed businesses overlaid on a camera view, giving you that “augmented reality” all the kids are talking about these days. It's a neat hack for hungry travelers, or a deadly distraction for those trying to skirt impulse purchase pressure.
