The Washington Post has launched The Social Reader application, built on Facebook’s new Open Graph. The Newspaper For Facebook offers users a personalized news reading experience, with front page stories pulled from The Post and its content partners.

Washington Post Social Reader is a free Facebook application that offers a new way to read news from The Washington Post and more of the Web’s best news sources — with your friends. Once you’re using the app, the stories you read will be instantly shared with your friends, and your friends’ reads will be shared with you, creating a socially powered newswire of intriguing articles.

WP Social Reader uses your likes, your interests, and what you and your friends are reading to deliver a set of stories tailored just for you. The more time you spend with the app, the better it gets to know you.
