In exchange for making our social lives more convenient, Facebook seizes the right to transform our sociality into commercially useful information, turn our relationships into market research and use that data to anticipate and shape our future selves with the ads it calculates that we should be presented with. It manages our friendships and then processes the data interrelationships to guide the process of how we subsequently develop our identities through its site. Since it is mediating our friendships, and in effect making the effort for us, it is also directing what the fruits of that effort will be, supplying the framework through which friendships develop and making itself the very medium of friendship.
