Call it the goosebump factor.
TED stands for Technology, Entertainment, and Design and the TED motto is “Ideas Worth Spreading”. The TED conference is held each year in California and brings together some extraordinary “thinkers and doers” to share (up to 18 minutes or so) their thoughts. Search the talks by theme, speaker, even most discussed. The talks are free to view online and there is even a blog to keep up with updates.
I think you’ll agree- high goosebump factor.
