Facebook ha lanciato Slingshot il servizio di messaggistica instantanea orientato a video e foto che si autocancellano una volta ricevuti in stile Snapshot.
To get started on Slingshot, shoot a photo or video. It can be what you're up to, who you're with or a quick selfie. Add some text and color, then sling it to a bunch of friends. Here's the deal: friends won't be able to see your shot until they sling something back to you. They can then reply with a reaction--or simply swipe your shot away.
