Future of The Web : Sir Tim Berners-Lee

This is a webcast of Sir Tim in Oxford recently (we were supposed to be going – but ultimately coudn't make it) talking about the Future of The Web. 

Abstract:
The development of Web technology has
been an exciting ride, a series of socially motivated technical
innovations some languishing, others catching on in a viral way. As
each development has suggested many new ones, and much of the original
vision is still unfulfilled, there is a lot to do. This talk will
discuss new challenges and hopes for weblike systems on the net.
