The guy standing between Facebook and its next privacy disaster

Shamed by past mistakes and weary of angry regulators, Facebook has transformed the way it makes new products and privacy controls, making all of the information we pour into the site on a daily basis far less likely to be used against us.

The face of the new, privacy-conscious Facebook is Yul Kwon, a Yale Law grad who heads the team responsible for ensuring that every new product, feature, proposed study and code change gets scrutinized for privacy problems. His job is to try to make sure that Facebook’s 9,199 employees and the people they partner with don’t set off any privacy dynamite. Facebook employees refer to his group as the XFN team, which stands for “cross-functional,” because its job is to ensure that anyone at Facebook who might spot a problem with a new app — from the PR team to the lawyers to the security guys — has a chance to raise their concerns before that app gets on your phone. “We refer to ourselves as the privacy sherpas,” says Kwon.
