Facebook announced today that Scribd has expanded its Facebook-based instant personalization. 

"While it’s rare we read together, reading can be social," says Facebook Platform product marketing manager Fran Larkin. "People share articles on Facebook, form book clubs, get book recommendations from friends, and debate and discuss news stories. Now Scribd, a social reading and publishing site, is making it easier to find great reads through the help of your friends." 

"Starting today, when you visit Scribd while logged into Facebook, you will see personalized reading recommendations based on what your friends are sharing and on your Facebook likes and interests," adds Larkin. "And when you find something that you enjoy, with a simple click of the Like button, you can quickly and easily share it with your friends. Through instant personalization, Scribd will use the public information you share with your friends on Facebook to personalize your reading experience."

About a week and a half ago, Facebook announced a similar move from movie review site Rotten Tomatoes, adding instant personalization to that. 

When Facebook first launched its Open Graph, the company partnered with Scribd to integrate its social plug-ins. The same day, Scribd launched Readcast which enables users to share what they are reading and publishing to their friends on Facebook and other social networks.

According to Facebook, over 55,000 items on Scribd are shared every day.
