Facebook kicks off its f8 developers conference in San Francisco on Thursday, with a keynote from founder Mark Zuckerberg, who is expected to announce big changes to the social network.
Zuckerberg's keynote comes a day after the company rolled out a flurry of new features--which some of its 750 million-plus users are already unhappy about.
The Cutline will be liveblogging the keynote. You can follow along here via the f8 livestream.
All times Eastern, and approximate:
1:20 p.m: Andy Samberg takes the stage as Mark Zuckerberg "We're going to change the universe!" Samberg, as Zuckerberg, says. "I say that every year."
1:22 p.m.: Samberg/Zuckerberg lists examples of what you should and shouldn't share on Facebook: "You wake up take a big number two, don't share that with your friends. That's for Twitter."
1:24 p.m.: The real Zuckerberg interrupts Samberg in an awkward prepared bit.
1:26 p.m.: Zuckerberg, still giggling from the Samberg appearance, begins his keynote in earnest.
1:29 p.m.: "People feel intense ownership over their profile," Zuckerberg says, calling it the most important "product" Facebook has in its social arsenal. "People put everything in there."
1:31 p.m.: Zuckerberg announces the first big change coming to Facebook, called "Timeline," a sort of super-sized, steroid-injected "newsfeed." It's a format where "your entire Facebook life has been condensed into one page," Zuckerberg says.
1:38 p.m.: "We wanted Timeline to be a place that you can really call your home," Zuckerberg says, unveiling a design that includes a large "cover photo" at the top. "You get a nice visceral feel."
1:41 p.m.: "You have complete control over everything on your Timeline," he says. "It's the story of your life, with all your apps, to express who you really are."
1:42 p.m.: The reviews of Timeline are already rolling in. "It's the future of Facebook," Gizmodo says. "And it's a tectonic shift."
1:45 p.m.: As with previous changes to Facebook, not all users are thrilled. "If we have an 'intense ownership' over our profile," one commenter wrote, "Why [can't we] leave it alone????"
1:52 p.m.: Zuckerberg announces "Ticker" a "lightweight" addition to its status update suite. "Until today, there was no way to express lightweight activity," Zuckerberg says.
1:55 p.m.: As expected, Zuckerberg says he has been working with more than a dozen partners music, film, TV and news companies to build a new class of social apps.
1:56 p.m.: First up Spotify, showing off an app that allows users to discover and listen to music through, and with, their friends. "It's incredible how much music you can discover through your friends," Zuckerberg says.
2:11 p.m.: Netflix CEO Reed Hastings, a Facebook board member, takes the stage to announce a partnership with Facebook. (It sounds like the Netflix app, in particular, won't be ready until some U.S. privacy issues are settled. Stay tuned, Hastings says.)
2:20 p.m.: On to a social news app "to discover what your friends are reading first." More than a dozen media companies, including Yahoo! News and News Corp., are partners with Facebook.
2:24 p.m.: Zuckerberg announces similar gaming and "lifestyle" apps--running apps, cooking apps--that users can add to their Timeline to "discover" new running routes, or recipes.
2:25 p.m.: All of these "open graph" social apps are aimed at achieving "real-time serendipity" and "finding patterns in your friends' activity," Zuckerberg says.
2:27 p.m.: Timeline will be rolled out "over the next several months."
