Mark Zuckerberg: The way that the mobile stuff is structured — Erick is really the lead PM for mobile stuff in general. I’m sure there’s specific things in there that aren’t announced yet. But he’s not running a secret project. That’s… I think that’s more like the type of stuff that Joe is working on or that Matt would typically work on.
Michael Arrington: The secret stuff goes through him?
Mark Zuckerberg: Not in general… I don’t think the secret stuff is that secret (Elliot Schrage: There’s some cool things, even if they’re not secret). There’s some stuff that hasn’t been announced, but there’s nothing like a fundamental departure from the strategy that I am laying out.
