Facebook Dating, an opt-in feature of the main Facebook app, will begin to tap into the content users are already creating across both Facebook and Instagram to enhance its service. Today, Facebook Dating users will be able to add their Facebook or Instagram Stories to Facebook Dating, in order to share their everyday moments with daters.

As opposed to more polished profile photos, Stories can give someone better insight into what a person is like by showcasing what activities they like to engage in, their hobbies, their interests, their personality, and their humor, among other things. And if the daters themselves appear in a Story, it lets others see what they really look like, even if their online photos are out-of-date.
