Using
Facebook on your Website allows you to create a more personalized,
social experience using Social Plugins such as the Like Button and
simplifies your registration and sign-in process using Login Button and
Registration Plugin.
Building
an app on Facebook gives you the opportunity to deeply integrate into
our core user experience. Use native Facebook functionality such as
Requests and Bookmarks to create an ideal social space for your users.
Facebook
Platform makes iOS (iPhone & iPad), Android and Mobile Web apps
social. Use Single Sign-On to access the user's social graph (without
yet another username/password) and create a personalized experience.
