Another redesign for Facebook on 6th birthday

NEW YORK -- In its latest redesign, Facebook is playing up applications, games and search.

The world's largest online social network has continuously morphed its home page as it's grown from a closed hub for college students to a Web and mobile destination for 400 million people.

Past changes have sparked protests from many users, though Facebook says it makes them to serve its audience better. Facebook says it conducts months of testing and often gets requests for such changes.

The latest evolution continues Friday after starting to roll out late Thursday, the company's sixth birthday. Links and items have moved around the home page as Facebook tries to streamline navigation and make games and apps stand out more.
