Remember Eduardo Saverin? The sad co-founder of Facebook who got strong-armed out of the company by Mark Zuckerberg in The Social Network (and also real life)? He's overcome his shattered dreams and is trying to get a piece of the next big tech thing.

Eduardo Saverin—the Facebook co-founder who isn't Mark Zuckerberg—made a rare public appearance last night, his first since The Social Network's release, it appears. Eduardo went to a Victoria's Secret party, where he mostly socialized with other tech nerds.

In The Social Network, Facebook co-founder Eduardo Saverin gets screwed. But Saverin writes, "The true takeaway for me was that entrepreneurship and creativity... are perhaps the most important drivers of business today." His $1.1 billion stake in Facebook probably helps.

The forthcoming Facebook movie exists thanks to an embittered co-founder who blabbed about the company's origins. Instant messages from CEO Mark Zuckerberg, below, describe the "dirty tricks" that made the co-founder so angry—and so indiscreet.

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?"

After years of freezing out cofounder Eduardo Saverin over a dispute about money, Facebook CEO Mark Zuckerberg has deigned to recognize his former Harvard buddy. Why now? Perhaps to derail a forthcoming Facebook tell-all?

We know what Facebook cofounders Mark Zuckerberg, Dustin Moskovitz and Chris Hughes are up to. Zuck lets COO Sheryl Sandberg run most of the company now while he plays industry visionary; Moskovitz is hiding from Valleywag's fearsome scrutiny; and Hughes is busy spamming your inbox with updates from Obama campaign director David Plouffe — sorry, revolutionizing politics on the Web. But where have unacknowledged cofounders Andrew McCollum and Eduardo Saverin gone? Their Facebook profiles aren't open to the public, but rival social network LinkedIn isn't nearly so skittish. Here are their profiles, with our notes:

We love legal proceedings. Statements are on the record, accessible to the public, and presumably truthful, since it's a crime to lie to the court. As supporting evidence for their sordid story of Facebook CEO Mark Zuckerberg's college days, Harvard-alum mag 02138 posted a series of court documents, including the transcript of Zuckerberg's deposition in one of the ConnectU lawsuits, and boy, is it a gem. The first tidbit: Mark Zuckerberg consides Eduardo Saverin a Facebook cofounder, along with Chris Hughes and Dustin Moskovitz. Or considered him one, during the April 2006 deposition. More recently, when we asked Facebook who its founders were in July, Eduardo was missing from the official list. No wonder: As 02138 revealed, Saverin, too, is suing Zuckerberg.

Earlier this week, CNBC asked me to come on the air to discuss Facebook's legal woes. Click to viewI've spent days immersed in legal filings, and the clip, above, just scratches the surface of what I've learned. Next week comes a critical moment for Facebook, the red-hot social network that has captured Silicon Valley's imagination, and its founder and CEO, Mark Zuckerberg. After the jump, I explain why Zuckerberg will face a moment of reckoning next Wednesday, July 25, and detail a timeline of Facebook's legal battles.

As Facebook's theoretical value soars, the interest of its hangers-ons grows practical indeed. I think that's why Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra are pursuing their lawsuit against sandal-sporting Facebook CEO Mark Zuckerberg with such tireless vigor. But the three Harvard school chums, who say they hired Zuckerberg to work on their competing ConnectU site before he launched what became Facebook, are far from the only ones pressing a claim to have been present at Facebook's creation. (For the record, long-suffering Facebook PR chief Brandee Barker says the company's official cofounders are Zuckerberg, Chris Hughes, and Dustin Moskowitz.) After the jump, a gallery of everyone who's not an official founder — but who'd like to be.
