“There’s plenty of blame to go around, but the list of actors has to start with Facebook. And for all its wonders — reaching nearly 2 billion people each month, driving more traffic and attention to news than anything else on earth — it’s also become a single point of failure for civic information. Our democracy has a lot of problems, but there are few things that could impact it for the better more than Facebook starting to care — really care — about the truthfulness of the news that its users share and take in.”
