I came here to post the same thing. Zuckerberg is only saying this because his buisness depends on it. Anyone who can get people to listen to them can report on people's opinions as a way to influence other peoples opinions. Considering the way the way the media echo chamber hangs on his every word, hes trying to create a self fulfilling prophecy.

People anxieties aren't fleeting after every update, what is fleeting are peoples assumptions that they can be open on facebook. These days, almost every time I take out my camera someone will inevitably asks me not to put the photos on facebook (not that I would anyway). Some friends have quit drinking because they know that if a picture of them drinking in their free time, which they are allowed to do could still ruin their career.

Facebook isn't making people more candid, its making us self-censor. That self censoring is moving from facebook back to the real world. Its very troubling.
