Facebook seems to be once again pushing users to check out the email addresses it handed out a long time ago. In the Contact Info section of your Facebook profile, you might be surprised to find that the only contact email address the social network displays is your @facebook.com email address. You can re-enable showing your other email addresses by clicking "Edit" within the "About" section of your Facebook Timeline.
Facebook commented, via email:
As we announced back in April, we've been updating addresses on Facebook to make them consistent across our site. In addition to everyone receiving an address, we're also rolling out a new setting that gives people the choice to decide which addresses they want to show on their timelines.
Ever since the launch of timeline, people have had the ability to control what posts they want to show or hide on their own timelines, and today we're extending that to other information they post, starting with the Facebook address.
While it sounds more like a glitch that the only email address visible to friends is your Facebook email address, the fact remains: if you want people to find your personal email address on Facebook, you'll have to spend a minute updating your settings. If this is Facebook's way of saying "use our email addresses," it's certainly not going to go over well with users.
Update: We just got off the phone with Facebook spokesperson Meredith Chin, who assured us that the changes to visibility on your profile are in order to put everybody on the same page once individual email show/hide toggles were instated recently. "We want everybody to use whichever service they want to use," Chin said. Facebook would've hidden your @facebook.com email address too, if it were any matter of privacy — except since your Facebook email address is the same as your profile URL, people have access to it anyway. To summarize, the point was to make everybody's personal email addresses private until each user unhides each one manually, since the site now allows more granular email visibility settings.
