5 levels of audiences: Low - random curious strangers at the airport - send them to TED.com

Guarded - friends, coworkers, family: TED is an exclusive event to go to hobnob with the smartest nerds I've ever met

Elevated - a first date: Show off with famous people, like Al Gore

High - The IRS: Make an effort to explain  what TED is.

Severe - Yourself: Remember your TED moments.
