In advance of Facebook’s major advertising announcement in early November, the preeminent social networking platform inked a ad distribution deal with Microsoft for $240 million, or a 1.6% stake in Facebook. Add in the other 98.4%, and in Microsoft’s eyes, Facebook is worth $15,000,000,000. Mark Zuckerberg, then, is worth anywhere from $3-5 billion. If/when someone buys Facebook, or when it goes public, the actual market valuation may be less than $15 billion, but really, once you have 9 zeros, does it really matter?

For all you Harvard students out there, you might want to do a comparison and see if it’s really worth sticking around for the degree. Could there be a Silicone Valley anti-Skulls & Bones led by Bill Gates? If so, Mark Zuckerberg surely is the newest member.
