Wow. Now  I am agreeing with Sean Parker.  From The Verge:

Parker says the social networking site exploits human psychological vulnerabilities through a validation feedback loop that gets people to constantly post to get even more likes and comments. […] In other words, using Facebook is like junk food: you get instant gratification when you post for likes and comments. It’s quick and easy but has little substance.
