What would a publicly traded Facebook mean to users? For the past couple of years, the potential for Facebook to go public has been bandied about a lot in tech circles, with more and more of the digital tea leaves suggesting that the social-networking juggernaut will, in fact, one day become a publicly traded commodity. The speculation has heated up again this week. And, amid all the chatter about financial disclosures and initial public offerings, another question has emerged: What would it mean for the average Facebook user? The Wall Street Journalthis week quoted unnamed sources who said Facebook is "inching closer" to a public offering, in spring or early summer, that would value the company at more than $100 billion. According to the report, Facebook would look to raise a staggering $10 billion during its initial public offering. A $100 billion valuation would price the social-networking giant at more than twice the value of tech institutions such as Hewlett-Packard Co. and 3M Co., the Journal reported.
