What does Facebook like button represent for App Store apps? On an iOS application's App Store reviews tab, there is a Facebook like button.

Anybody know what it does when a user clicks on it? Does it show on the user's Facebook feed or does it like a Facebook page for the app?
If you are logged in Facebook from Setting app, then it will show the "Like button" on App Store app detail.

It will like the application URL from your account.
