There’s the short 18 minute or less TED talk experience you get from watching one of these presentations online in the comfort of your own browser. And then there’s the experience you get from spending a day with a large group of people watching a sequence of presentations that flow together around a theme and then talking about the ideas with each other. It’s like the difference between watching a play on television and going to a live performance.
Just like there’s always room for another live performance of theater or music, there’s always room for another set of ideas passionately presented in a live setting and then discussed by an engaged audience, whether it’s a branded TEDx event or under some other name and in a different style. There can’t be too much of it in the world right now.
From "A day at TEDxRainier" by James Duncan Davidson
