I love listening to some of the TED talks!
The place I work at (art museum) holds simulcast viewing of the national TED talks. Very distracting on those days - I always want to sneak into the auditorium and watch instead of do my job!
There are also locally held TED events. Our museum director gave a speech at our local TED event. If you are interested in these talks, you might try and find a local TED event. But if you do want to go to a local on, get your tickets as soon as possible. I know locally our TED events always sell out.
