facebook开发应注意的5个原则

Solve a real world problem that's inherently social. For an example, Cat pointed to GroupCard, which is an electronic version of those cards passed around the office for everyone to sign. 

"Flexibility," says a Facebook rep. Developers need to be able to "work fast tweaking your app in response to user feedback." Pro tip: Tweak even faster when Facebook tells you to, too.

Cat told us that about a fifth of the top 25 apps use Facebook Connect, which allows users to use their Facebook IDs on other Internet sites. Cat mentioned another app that functions mostly on user's iPhones. The point: It's probably good if your app helps Facebook extend its reach off Facebook.com.

Push the limits with user Notifications. Facebook tells us that realizing how well user notifications help an app grow with users is the main eureka moment contestants have after they start working with Facebook's internal developers.

Be marketable. That's the whole point of this. Each of the 25 finalists created a commercial for their app and Facebook pointed us to five of them in particular. Use these videos as a model for your own next year: Teach the People, Good Call Sports, GroupCard, RealGifts and vDream Racing.
