Mark Zuckerberg, at today’s Facebook F8 Developer Conference, announced a new feature called Share Sheet. It’s designed to make posts more attractive and predictable, as well as target them to specific users.
“Today there are more than a dozen ways of sharing from an app into Facebook,” Zuckerberg said. “People want to be able to share into messages and groups and not be surprised about what it will look like.”
Share Sheet lets you preview your post before it reaches your Facebook feed and offers options to share with particular people.
