why I'm quitting facebook

cnn | We Facebook users have been building a treasure lode of big data that government and corporate researchers have been mining to predict and influence what we buy and for whom we vote. We have been handing over to them vast quantities of information about ourselves and our friends, loved ones and acquaintances. With this information, Facebook and the "big data" research firms purchasing their data predict still more things about us -- from our future product purchases or sexual orientation to our likelihood for civil disobedience or even terrorism.

The true end users of Facebook are the marketers who want to reach and influence us. They are Facebook's paying customers; we are the product. And we are its workers. The countless hours that we -- and the young, particularly -- spend on our profiles are the unpaid labor on which Facebook justifies its stock valuation.

The efforts of a few thousand employees at Facebook's Menlo Park campus pale in comparison to those of the hundreds of millions of users meticulously tweaking their pages. Corporations used to have to do research to assemble our consumer profiles; now we do it for them.

The information collected about you by Facebook through my Facebook page isn't even shared with me. Thanks to my page, Facebook knows the demographics of my readership, their e-mails, what else they like, who else they know and, perhaps most significant, who they trust. And Facebook is taking pains not to share any of this, going so far as to limit the ability of third-party applications to utilize any of this data.

Given that this was the foundation for Facebook's business plan from the start, perhaps more recent developments in the company's ever-evolving user agreement shouldn't have been so disheartening. Fist tap Arnach.
