Keen On? Bob Metcalfe: Yes, There Is a Social Networking Bubble (TCTV)

When Bob Metcalfe says that there?s a social networking bubble, we should take notice. Inventor of the Ethernet, coiner of Metcalfe?s Law, founder of 3Com, a technology pundit and publisher at InfoWorld, VC at Polaris Ventures, and now Professor of Innovation at the University of Texas, Metcalfe is one of the true pioneers of Internet technology and business. But, in spite of Metcalfe?s sense that the social networking bubble will burst, he remains bullish about innovation on the Internet. In particular, he sees three sectors which are about to be radically disrupted by the Internet: healthcare, education and energy. That?s where we're going next, Metcalfe predicts. So forget about your social media start-up, he advises, and focus on reinventing the education, healthcare and energy industries.
