Chuck Marohn, the executive director of Strong Towns, explains the difference between a road, which is a connection to two place and a street, which is a network of activity. He stresses the importance of returning roads to towns for community and economic development.
In the spirit of ideas worth spreading, TEDx is a program of 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. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations) – TedxTalks on YouTube
