TED is a small nonprofit devoted to Ideas Worth Spreading. It started out in 1984 as a conference bringing together people from three worlds: Technology, Entertainment, Design. The conference has evolved and now drives the world's most fascinating thinkers and doers to give the talk of their lives in 18 minutes. Since most of us don't get a chance to listen to these discussions live, it's great that TED makes them available online. TED via Gizmodo
