Web 2.0 Summit (formerly named Web 2.0 Conference) brings the intelligence, innovation, and leadership of the Internet industry together in one place at one time. Through incisive plenary sessions, frank onstage conversations, rapid-fire “high order bits,” and Launch Pad, visionaries and executives from Internet businesses present their unique perspective on the Web’s future-in-flux. Web 2.0 Summit is brought to you in partnership with O’Reilly Media, Inc. and TechWeb and moderated by John Battelle, Program Chair, and O’Reilly CEO and founder, Tim O’Reilly.
