Facebook has launched a new Timeline feature that automatically syncs your Timeline address and your email address and is expected to begin rolling out over the next few weeks.
The new program means that if your Timeline address or vanity url is facebook.com/bandwidthblog for example, then your Facebook email address will be email@example.com.
Anyone who has previously selected an email address will be unaffected.
While Facebook launched vanity URLs for users back in in 2009, there was no email address component. It was only later in 2010 that the social network gave users @facebook email addresses although its likely that most users would have preferred the email addresses they already had. Google+ on the other hand is heavily interlaced with Gmail which may have been the incentive behind this new move.
The latest change seems to be aimed at users who didn‘t change to a vanity URL, which automatically netted a synchronized email address.
