Facebook announced yesterday that it will go public sometime this spring with an initial public offering valued at $100 billion. Sure, the site has lots of users who “like” it, but should they consider buying the stock? Today on my show, I put that question to The Motley Fool’s Chris Hill. I also asked him whether Facebook can be as much of a Wall Street success as Google and Amazon, or is it likely to remind people of AOL and Netscape? And how does it compare to the IPOs of other online companies, like Zynga, Groupon, and LinkedIn?
