Yahoo announced Wednesday a partnership with Facebook that will enable the two sites to share certain parts of their streams.

Yahoo email account users will be able to check Facebook status from their inboxes. The service will also be available across other Yahoo properties, including News, Answers, and Sports, thanks to Facebook Connect.

In turn, Yahoo users can share content like ratings, photos and article comments directly onto their Facebook streams.

Yahoo users should expect to see Facebook integration in the first half of 2010.

As the place where over 500 million people visit every month, Yahoo!'s goal is to bring together social experiences from across the web, and provide one place for people to access information and stay in touch with the people they care about most, Jim Stoneham, vice president of communities for Yahoo, wrote in a blog post.

In the future, you'll be able to choose where you want to update your status message - from destinations across Yahoo! - or directly on Facebook.

Stoneham told the NYTimes that there's no money exchange in the five-year deal as of yet.

For Facebook, it gives the social networking site yet another opportunity to grow beyond its current 350 million users who could potentially sign up from Yahoo, given they already don't have Facebook accounts.
