"A tweet may not look like much, but its value lies in the mental dimension. You use Twitter, Facebook, MySpace, and other Web services to construct a complex meld of stories, images, and feelings in your mind. No single bit seems weighty on its own, but the resulting blend is rich in joy, emotion, and suspense. This is a new form of drama, and it plays out inside us — with technological assistance — rather than on a public stage. Online, you can literally create your own economy. By that, I mean you can build an ordered set of opportunities for prosperity and pleasure, analogous to a traditional economy but held in your head."

Brilliant economist Tyler Cowen.
