Facebook's answer to Snapchat, Messenger Day, is now being rolled out to users worldwide. The premise is simple. You use Messenger’s built-in camera to snap pictures or videos; add text, doodles, cartoon overlays, or facial filters; and then drop this content into a little digital bundle (your “Day”) that all or some of your friends can access, and that deletes itself every 24 hours.
Will you be using it?
