LinkedIn shares have been up about 19 percent for much of the morning following better than a expected earnings report yesterday. The company grew revenue by 81 percent to $304 million, and saw similar growth in net income. LinkedIn continues to be the lone bright spot amid a dismal run of consumer Web IPOs, but a few more quarters like this and those in the Valley may slowly forget about the Facebook, Groupon, and Zynga debacles…ok maybe that’s asking a little much.
