I think that these tags are awesome. I saved my tag to display my Facebook profile page. I have seen other tags used to scan blackberry phones between users. It is just an interesting way of displaying information and a fast way to access certain urls or what ever content you find yourself with. I personally think that tags can be useful because they are simple and fast. Rather than having to log into Facebook and then logging into my account just to view my profile, I can now use a tag reader to quickly access the url of my Facebook page.
