The original TED (Technology, Entertainment, Design) conference is an extremely pricey idea-fest that I wish I could attend but can't.
There's also a growing collection of TEDx events: "local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group."
TEDxCLE returned to the Capital Theater last Friday but I wasn't able to attend. I'm looking forward to watching videos of the talks, scheduled to be posted on their website in the next week or so.
