Privacy on
The tool is lacking a crucial component for most users though. "To preview how your profile appears to a specific person, like a friend or coworker, type their name into the open field and press enter," says Facebook. But what if the co-worker is not your friend, but is instead a "friend of a friend." As Randi Zuckerberg, the sister of Facebook's CEO discovered to her extreme dismay, "friends of friends" on Facebook sometimes have access to content on our profiles that we wouldn't expect, such as an intimate family photo that Zuckerberg thought only her friends would see.
I've had at least one friend "unfriend" me just so I could tell him what was visible on his profile to someone one degree of separation away from him. He wanted to know what people in the dating pool would see on his profile if they knew his friends. It's also highly relevant for employment purposes if it's possible that a human resources person reviewing your file has a friend in common with you. I asked Facebook's chief privacy officer Erin Egan why there isn't an option to see what Facebook users "one hop away from us" -- as the NSA would say -- can see. The question seemed to surprise them.
“We’re trying to balance options while keeping it simple,” says Egan. "We've never gotten feedback about that before."
Egan says the company might reconsider this if they actually heard from users that it was something they wanted. Privacy has become such an issue for Facebook that they invite users to ask the company's CPO questions directly. So if this is a feature you're interested in, you might want to make yourself heard here.
