Facebook is hosting its second F8 developers' conference today in San Francisco. Facebook CEO Mark Zuckerberg is giving the keynote 1:30 p.m. PDT. I'm in the audience and have live coverage of his talk. See below; I'll go live when he takes that stage. Facebook is also hosting a video stream.
Highlights of the talk will likely be Facebook's new design, a discussion on openness, mobility, monetization, and a new tiered system to give some apps more access to Facebook users' data than others.
