TEDTalks operate on the simple premise of asking smart, creative people to talk about something that excites them. In under 20 minutes. The result is a treasure trove of brilliant ideas. Here are a few of my favorites, but you might want to spend some time browsing through their site. There is no shortage of great talks.
The first talk is by Ethan Zuckerman, now at Harvard’s Berkman Center for Internet and Society, warning that the Internet can close minds as much as open them. The second is by statistician Hans Rosling explaining why the future looks bright. And the third is by Jane McGonigal explaining the power of gaming.
There is also a local version at TEDxTampaBay.
