An incredible breakdown of social media using Freud's psychoanalytic personality theory. I've done a lot of work on myself over the last few years to keep my viciously hyper vigilant superego in check, allow my ego to become fortified in a healthy manner while still allowing my primal ID to express itself. I have a long way to go, but it has freed me from much physical and psychic suffering. The only thing I would add to this diagram is Tumblr, which I would probably throw at the bottom. I find Tumblr to be a great release for the ID. I'm also curious as to where LinkedIn would be on this, I'm guessing in the middle, or perhaps near the top. It's also missing Pinterest, which I think falls into the top as well, with elements of all three. Isn't this cool?
