Thanks to
Omar's blog I went and checked out the beta of Tag. This is really cool. Basically I created my tag and took it's picture...and it worked. If you would like to give Tag a spin, you can download the free app to your mobile device. Then take a snapshot of my tag below or create a tag of your own to try.

I would love to start seeing tags on billboards (don't do this while driving) and commercials. Microsoft, in my opinion, doesn't have the marketing department to pull that off. But it would be cool.
