TED: world's greatest thinkers and doers

Here is one community worth joining:

"TED"
Ideas worth spreading
by the world's greatest thinkers & doers.

Videos. Free. Online.
And a community of high level minds.
The only community I have felt compelled to join.

TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader.

The annual conference now brings together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes).

This site makes the best talks and performances from TED available to the public, for free. More than 60 talks are now available, with more added each week. These videos are released under a Creative Commons license, so they can be freely shared and reposted.

Mission: Spreading ideas.
