What blows my mind about what you're describing is how ill-equipped society was for Facebook, and how laughable it is that Mark Zuckerberg is in charge of reconciling Facebook and society, for the very reasons you're talking about.
When I think about the global scale and social/political/economic scope required to responsibly run Facebook, and compare that to the skill set of Mark Zuckerberg it's just, like, insane that he's in charge of it. I'm sure Mark Zuckerberg is truly brilliant and capable of becoming a great international leader. No doubt. I just don't think it should be, like, his first job. Lol. It's truly absurd.
