Facebook CEO says he'll double down on privacy

SAN FRANCISCO (AP) — Facebook CEO Mark Zuckerberg laid out a new "privacy-focused" vision for social networking.

He promised to transform Facebook from a company known for devouring the personal information shared by its users to one that gives people more ways to communicate in truly private fashion, with their intimate thoughts and pictures shielded by encryption in ways that Facebook itself can't read.

Zuckerberg laid out his vision in a Wednesday blog post , following a rocky two-year period in which the company has weathered a series of revelations about its leaky privacy controls.
