“Social media is a short-form medium where resonant messages get amplified many times. This rewards simplicity and discourages nuance.” The medium, he continues, often “oversimplifies important topics and pushes us toward extremes.” This insight might have led Zuckerberg to a forthright accounting of the limitations of Facebook as a communications system. He might have pointed out that while Facebook is well designed for some things — banter among friends, the sharing of photos and videos, the coordination of group actions (for better or worse), the circulation of information in emergencies, advertising — it is ill designed for other things. It’s lousy as a news medium. It’s terrible as a forum for political discourse. It’s not the place to go to get a deep, well-rounded view of society. As a community, it’s pretty sketchy. And, he might have concluded, if you expect Facebook to solve the problems of the world, you’ve taken me far too seriously.
