Summary Box: Facebook looks to extend sharing

WHAT FACEBOOK IS DOING: As it grows, the company is trying to evolve from an Internet hangout where people swing by to share tidbits, links and photos to a homestead full of the memories, dreams and diversions of its 800 million users.

MORE CHANGES? In a conference Thursday, CEO Mark Zuckerberg unveiled a dramatic redesign of its users’ profile pages to create what he called a “new way to express who you are.” It’s called a “timeline,” an online scrapbook of your life.

MUSIC, MOVIES AND MORE: Facebook also announced a slew of new partnerships with music, entertainment and media companies that center on letting people share what they read, listen to or watch.
