Is Net Neutrality essential for democracy? What role will AI have in the future of the web? What will Web 4.0 look like? On June 11, in an attempt to answer these and other questions, Tim Berners-Lee and other leading web authorities will gather at the Rensselaer Polytechnic Institute in Troy, N.Y., for an old-fashioned debate with a social media twist: The content of the debate will be collaboratively created by web users, who can submit questions and promote them through a user-based ranking system similar to Digg. The most popular questions will form the basis of the debate, which will be webcast live. Viewers will also be able to interact with the panelists by submitting questions and comments in real time.
