This may be old news to a lot of you but I was recently pointed in the direction of TED. TED stands for Technology, Entertainment & Design and they are a series of talks by a series of "facinating thinkers and doers". Over 200 of previos talks have been archived and are available to view online. One that may be of particualr interest is a talk by Brewster Kahle, who has some very interesting things to say about archiving the web.
Check it out.
