Is there anyone left who doesn't believe LinkedIn (NYSE:LNKD) is the world's most impressive social network? Sure, Facebook is bigger and Twitter has proved itself brilliant at delivering news in real time, but of them all it's LinkedIn that hoards profits like Scrooge McDuck.

The company's fourth-quarter results destroyed analyst estimates. Revenue soared 81% as adjusted profits beat estimates by a whopping $0.16. Talent Solutions, the business unit that serves hiring managers and recruiters, soared 90% year over year. The stock popped more than 20% on the news.

Yet LinkedIn's run is far from over, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova. In the following video, he shares the one metric that shows the company has long since graduated from its days as a resume disrupter. Please watch, and then be sure to leave a comment to let us know what you think.
