"Here is what [Ghonim] concluded about social media today: 'First, we don’t know how to deal with rumors. Rumors that confirm people’s biases are now believed and spread among millions of people.' Second, '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. Third, online discussions quickly descend into angry mobs. … It’s as if we forget that the people behind screens are actually real people and not just avatars.'
'And fourth, it became really hard to change our opinions. Because of the speed and brevity of social media, we are forced to jump to conclusions and write sharp opinions in 140 characters about complex world affairs. And once we do that, it lives forever on the Internet.'
Fifth, and most crucial, he said, “today, our social media experiences are designed in a way that favors broadcasting over engagements, posts over discussions, shallow comments over deep conversations. … It’s as if we agreed that we are here to talk at each other instead of talking with each other.'”
I think the lesson is that if you have 1 simple goal, social media can help you reach that. If you have a complex goal, like turning a country from dictator to democracy, that is where things break down.
