[todo] take advantage of text, image, sound, and video recognition technology!

In my future development of apps, I may be able to implement combination of text, image, sound, and video recognition technology to improve the apps understand users' context.

Hope the showcase of text and video recognition technology from F8 conference this March can come out as API/SDK sometime soon.

In the meantime, learned available APIs/SDKs like below.

• Wikipedia: List of open APIs
• ProgrammableWeb: API directory, SDK category, showcase, how-to
• Mashape: "Largest API Marketplace And Powerful Tools For Private And Public APIs"

For creating a useful web service, I need to dig deeper into mashup!!!
