This has been one of my favorite Ted Talks of all of time. It comes from Clay Shirky.
From his TED Talks bio:
“Shirky is an adjunct professor in New York Universityʼs graduate Interactive Telecommunications Program, where he teaches a course named “Social Weather.” Heʼs the author of several books. This spring at the TED headquarters in New York, he gave an impassioned talk against SOPA/PIPA that saw 1 million views in 48 hours.”
Watch and learn.
