Tim Weninger, an assistant professor of computer science and engineering at the University of Notre Dame, describes a study he conducted on reddit.com in which he had a computer program up-vote or down-vote the latest post every two minutes. As he explains, the experiment shows that early random up-votes makes a post 20 percent more likely to appear on the front page. His conclusion? Just one quarter of one percent of viewers determine what the rest of the site's readers see—so don't believe every trending content rating you see online.

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)
