Well, the contentious rumors have been confirmed: Justin Timberlake will play founding president Sean Parker in a little film entitled The Social Network, which everyone else just calls "that Facebook movie." Meanwhile, Jesse Eisenberg will play founder Mark Zuckerberg. [AFP]

What advertising depression? Mark Zuckerberg announced Facebook is cash flow positive a year ahead of schedule, hitting 300 million users and growing ad sales. Great. Now the social network needs to achieve actual profit, and ditch its beloved funny numbers.

Scriptshadow, which obtained the first leaked script for Facebook movie The Social Network, now claims to have casting choices, including Justin Timberlake as Napster's Sean Parker. News In Film created this handy graphic.

FriendFeed grew out of Google's casual engineer culture, and the team didn't bother dressing up to sell the social aggregator to Facebook for $50 million, either. This picture does indeed speak volumes.

Mark Zuckerberg was photographed in intimate conversation with Microsoft's former CTO in Sun Valley last week. The Facebook founder might simply have been quizzing Nathan Myhrvold about Zuckerberg doppelgänger Bill Gates. But there's a more interesting possibility.

The blog ScriptShadow got hold of the first draft of Aaron Sorkin's Facebook movie. The verdict? The movie reads oddly mesmerizing, and has an unexpected hero: Sean Parker, an early investor in the social network.

It's that time of year again, time for the Allen & Co's annual media industry confab in Sun Valley, Idaho. Occasionally described as a "summer camp for billionaires," the Herb Allen-hosted event is expected to atrract more than 250 media chiefs, tech moguls, financiers, Hollywood agents, and politicians, as well as the odd sports star or two. (LeBron James will be putting in an appearance this year.) Mostly, however, it will be populated by the sort of people who make it a point to show up every year, people like Bill Gates, Warren Buffett, Barry Diller, Sumner Redstone, and Rupert Murdoch, all of whom will undoubtedly be photographed over the coming days taking part in one of the many leisure activities arranged for attendees, like rafting, yoga, chess, bridge (a particular fave of Buffett and Gates), and biking (see Diller, left).

Ben Mezrich's forthcoming Facebook exposé was sold to film producers before it was even written. The Hollywood influence helps explain why the book answers such pressing questions as, "Who might the co-founders have conceivably boned, and where?"

Facebook's creation myth has left the building, or so we hear: Fortune is said to be readying an excerpt of Ben Mezrich's tell-all book and movie about the social network. And another publication is, naturally, trying to ruin the scoop.

Facebook settled a long-running trademark suit from Aaron Greenspan (pictured), the Harvard student whose "Universal Face Book" system predated Facebook and was used heavily by its founder before he publicly branded his own social network. Greenspan is just the latest mess Facebook has tidied up.

Dear Ryan:

As I head to NBC to run its Bay Area site, I'm leaving you one Silicon Valley gossip blog, used but in good condition. A few thoughts on how to keep it that way.

Had an awesome week? Whatever. It was not as totally awesome as the week of Twittering Facebook chanteuse Randi Zuckerberg (of the Mark Zuckerberg Zuckerbergs). Except for the part where Julia Allison stalked her!

Mark Zuckerberg, Facebook's CEO, is once again courting software developers. Where he once invited them to live on its site, he's now hoping they'll knit Facebook into desktop applications. It's another move to ape Twitter.

Owen Van Natta, Facebook's former COO, is officially taking over MySpace, News Corp.'s social network. With its user numbers stagnant, MySpace desperately needs a restart. Is Van Natta the guy to do it?

Former Facebook COO Owen Van Natta is the frontrunner to replace Chris DeWolfe as MySpace CEO. Blog lordling Jason Calacanis has been jokingly nominated for the News Corp. gig. Here's who should get it.

Facebook's revenues are reportedly up 70 percent from last year, when they came in between $250 million and $300 million. What's their magic trick? Junky ads with catchy photos!

How do engineers decide which jobs to take in Silicon Valley? It's a complex algorithm involving money, friends, hype, and free food. Nowhere in the equation: slick videos. That's why Facebook's recruiting is failing.
