A Reuters article noted LinkedIn's strong showing in the fourth quarter of this past year, when its revenue of $167.7 million exceeded Wall Street's expected $159.7 million. At the same time a year earlier, revenue for the fourth quarter only totaled $81.7 million. And more money is expected to trickle in; the company, which went public in May, set a revenue estimate for 2012 in the range of $840 million to $860 million. Expectations were also strong outside the company: "Average Street estimates for the full year 2012 were $828.2 million in revenue."

Reuters credits the company's increased revenue "to strong product and subscription growth."
