This is about sharing to facebook, and this is why twitter works hand in hand where people see something they like and they want to share it via facebook, now they can share it inside the app instead of closing out and going into the facebook app everytime they need to share something.
What????????? Closing out apps? What version you running of IOS??? You don't have to close out of the app.
Just skip it. Trust me, No one really cares where you've "checked in", how much you had to drink, what celebs you saw or what your kids are doing
