Facebook's all about sharing -- pictures, life changes, embarrassing details that may get you canned by some future employer. But what about information from third-party apps that you don't want clogging up your feed? Facebook's been rolling out an update that'll make it necessary for apps using the service to ask your permission before going ahead and posting, say, your workout routine to everyone you know -- a feature that, granted, a number of apps already have in place. Also new is a faster Login -- 31 percent faster by Facebook's measure. The social network has also taken the opportunity to mention that it's been working with the makers of popular apps to improve the login experience all around, including some unspecified future updates to the service.
