Facebook is fine-tuning not only how you share stuff, but what content you see after you share.
That’s the goal of an update to its iOS app that is designed to cut down on accidental oversharing by giving users a preview of their posts before they go live. It could be something you don’t want the whole Facebook world seeing, like the embarrassing TV show you’re currently watching.
In a related experiment, some users of the main Facebook app are also seeing additional content suggestions from Facebook after posting.
