A great metaphor for the Net effect on digital natives' lives is used by the University of British Columbia, which has a whole Web site about the "digital tattoo," with a tutorial on how to "Protect," "Connect," "Learn," and "Work" with the Net effect. Here's how UBC explains it: "Just like a tattoo, your digital reputation is an expression of yourself. It's highly visible, and hard to remove. Explore how your online identity affects you, your friends, your school and your job – for better and for worse – and how to make informed choices." I found out about this resource in a Toronto Globe & Mail article, "Chances are your kids are savvier online than you think."
