My chances of every being able to afford or be smart enough to get into a TED conference, are as likely as getting tickets for an Arsenal football match. But hey, most of the events and speakers are online.
Seriously, this resource is immense, if you haven't had a look, do visit and I'm sure you'll find an area and something of great interest. This has to be one of the greatest online resources, I have ever seen.
----- 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).
