If you still needed a reason to get a pair of Google Glass, well, here's four more: Twitter, Facebook, Ebay and Tumblr all revealed new applications for the glasses, which will undoubtedly up the fun-factor for the device—especially since the only other apps known in development were from the New York Times and Path. The Twitter, Facebook and Tumblr options will (of course) allow Glass wearers to snap a photograph and share it across their social networks, straight from the device. The Ebay option will make sure you don't miss your bid on those classic Air Jordans while you're on the move.
