WELCOME TO THE ON-LINE HOME OF TEDxNEWYORK.

TEDxNewYork is held at GreyNY, 200 Fifth Avenue. We meet every week (mostly) on Fridays now and (mostly) from 1-2pm. We are open to the public. If you want to attend, send a note to admin@tedxnewyork.com (that's Don McKinney & Chel O'Reilly) with your vitals. Our biggest limitation is space so give us plenty of notice and we'll do our best to accommodate. Hope to see you at one of our events soon.

Calling for a new priority:

"You should know what "two standard deviations from the mean" means. And I mean it."
