I agree with pastafarian, too verbose and dry. Can you come up with a personal experience or current affair where knowledge was a burden? - that might add impact. Are there situations where social media creates a knowledge burden? How about Wikileaks? Take the opportunity to use these essays to show who you are. Good luck!
BTW - Based on your profile, Northwestern (stretch school) and NYU (safe school) would be a good fit with your stated interests.
