Building an app on Facebook gives you the opportunity to deeply integrate into the core Facebook experience. Your app can integrate with many aspects of Facebook.com, including Requests, Bookmarks and Page tabs, making your app a seamless part of the Facebook experience. All of the core Facebook Platform technologies, such as Social Plugins, the Graph API and Platform Dialogs are available to Apps on Facebook.com.

Every page with a significant amount of Facebook page likes should have their own custom Facebook app.  Why? Engage with your fans in a unique way.  Facebook is the biggest platform, nowadays who doesn’t have Facebook? 600+ million users use Facebook.
