‘In Hamlet’s Blackberry, William Powers likens our digital age to a gigantic room. In the room are more than a billion people. But despite its size, everyone is in close proximity to everyone else. At any moment someone may come up and tap you on the shoulder—a text, a hit, a comment, a tweet, a post, a message, a new thread. Some people come up to talk business, others to complain, others to tell secrets, others to flirt, others to sell you things, others to give you information, others just to   tell you what they’re thinking or doing. This goes on day and night. Powers calls it a “nonstop festival of human interaction.” ‘ —Kevin DeYoung (“crazy busy”)
