The following video is from Friday's Motley Fool Money roundtable discussion, with host Chris Hill and analysts Jason Moser, James Early, and Ron Gross.

In this segment, shares of LinkedIn (LNKD.DL) jumped up 18% on Friday morning, after fourth-quarter profit rose 66%. The business networking site added 15M new members ... two per second for the quarter. The company also became the thirteenth most-visited website in the world. The guys discuss LinkedIn's moat, and whether it's larger than Facebook's (META 0.14%), and if it can keep up this level of growth.

LinkedIn is finally coming into its own, and leaving behind the stigma created by the ultimate social network, Facebook. After the world's most hyped IPO turned out to be a dunce, most investors probably don't even want to think about shares of Facebook. But there are things that every investor needs to know about this company. We've outlined them in our newest premium research report. There's a lot more to Facebook than meets the eye, so read up on whether there is anything to "like" about it today, and we'll tell you whether we think Facebook deserves a place in your portfolio.
