TED is a series of conferences that invite speakers to present 'ideas worth spreading'. There are over 700 TED Talks available to watch free online, with an impressive array of speakers. 

Now TED want Joe Public to join the ranks of Bill Gates, Al Gore, Richard Dawkins and.. Jamie Oliver. Anyone can send a one minute video 'audition' explaining their idea, and the best will get to present their ideas in New York. 

Will this talent-show approach dilute TED's quality, or broaden it's appeal by including great ideas from those who otherwise wouldn't have an opportunity to spread them? We'll see.
