Yahoo Unveils Y!OS

To make it clear, Y!OS stands for Yahoo! Open Strategy.

Here's how Yahoo! describes the initiative:

Through Y!OS, we're rewiring Yahoo! so that developers can tap into benefits once only available within Yahoo!. Namely, you can leverage the content, traffic, and user base of Yahoo! to extend your presence on the Web.

Whether you are just a small hobbyist or large company, the Open Strategy provides a new avenue for you to reach and connect with Yahoo! users like never before.

Y!OS consists of four major components: Yahoo! Applications Platform, Yahoo! Social Platform, Yahoo! Query Language, and OAuth Authentication.

Yahoo! envisions us to benefit from Y!OS in a number of ways:

• Use Yahoo! to connect potential users to your service
• Leverage Yahoo!'s built-in services to your benefit
• Promote your application to the largest online audience on the Internet
• Use Social Platform as a social-network-in-a-box
  

Y!OS allows to use a wide array of technologies for development for the Applications Platform.
