Is social media destroying our democracy?

Facebook and Twitter have become giant engines for destroying the two pillars of our democracy — truth and trust. Yes, these social networks have given voice to the voiceless. That is a good thing and it can really enhance transparency. But they have also become huge, unedited cesspools of conspiracy theories that are circulated and believed by a shocking — and growing — number of people.
These social networks are destroying our nation’s cognitive immunity (Links to an external site.) — its ability to sort truth from falsehood
–Tom Friedman/NY Times
