So says Andrew Marantz, the author of a new book on the topic. “We casually make the analogy between the internet and the public square, or the internet and a town hall, but it’s not really like that. It’s not an open space where everything is flat and democratic and everybody can speak their mind and look each other in the eye and get an equal voice and an equal time. The social internet is run by personalized algorithms, and the algorithms are run on emotional engagement.” – The New York Times
