Douglas Rushkoff in real life

Douglas Rushkoff's first book made him a tour guide to the Internet in the early 1990s and an early prognosticator of its potential. But much has changed between the awkward days of "the 'Net" -- then a non-commercial collection of public networks accessed by local ISPs -- and the overloaded era of Facebook and YouTube. If Rushkoff is well-versed in the language underneath the "digital revolution," he's also become one of its most outspoken critics.
