1. What does Wael Ghonim say are the “five critical challenges facing today’s social media?":
Challenge 1: We don't know how to deal with rumors. Rumors that conform people's biases are now believed and spread among millions of people.
Challenge 2: We create our own echo chambers. We tend to only communicate with people that we agree with, and thanks to social media, we can mute, un-follow, and block everybody else.
Challenge 3: Online discussions quickly descend into "angry mobs." It's as if we forget that the people behind screens are actually real people.
