OMG OMG OMG—Facebook's initial public offering is today, with sales of the social media stock going on sale at 8 a.m. PST. But founder Mark Zuckerberg and many others are becoming super rich off the $104 billion valuation. So what's left? Well, Zuck's new status update is "Listed a company on NASDAQ."

Nasdaq is, naturally, thrilled that Facebook decided to be listed on its exchange (over the New York Stock Exchange)—and the NYSE certainly doesn't have a Times Square display like this.

Nasdaq also allows IPOs to be listed later, after its 9:30 a.m. EST/6:30 a.m. opening bell.

Update: And here's video of Zuckerberg gleefully ringing Nasdaq's clangy bell from Facebook's campus in Menlo Park this morning:
