I've just discovered Shot Codes. It is a way to learn about a person's blog or website by scanning their "Shot Code". First you must register by visiting W-1.com and download a free mobile app. select a ShotCode, and purchase gear from the online store ( at $50 to $57 a pop). Owners can connect their symbol to an Web site. So, if you happen to see one of these unique logos at a club or event, you surreptitiously snap a photo of it with your phonecam and a tiny app directs you to the wearer's LinkedIn, Facebook, or MySpace profile. Then you can decide whether a "Hello" is in order.
