You might think their success has to do with the quality of the speakers, and that’s partially true, but the main reason extends much deeper. It includes a certain X factor that you never see on camera or while sitting back in the auditorium. For me the ‘x’ factor in TEDx truly are the organizers. For TED, it’s Anderson and his team. TED and TEDx make their events interesting because the Organizers are interesting. They select interesting themes, interesting speakers and interesting audiences (more on that later).
