In a way, I see utility in companies like Facebook openly exploiting whats possible with current technologies, web APIs, and mobile platforms so that privacy laws have a target of what to address and so that the general public can get a grasp of what's going on. It's better than it happening in the dark, behind the scences.

Before Facebook, if you tried to explain to a layman that your social data can be used to manipulate entire elections, people probably would have looked at you with strange and furrowed brows. Now, it's a question of the best way to address the issue.
