I love this TED Talk for many specific applications it suggests for education. For one, I love the graphic of dots representing people tweeting information online. Journalists can use the information to determine the most influential online voices. It's a compelling image of the distribution of information.
I am also interested in what Nolan's work as a journalist tracking facts online suggests about engaging students in determining authentic information.
Consider too what it offers as a caution to students publishing video and images online. Take a look.
