I've seen the $10-billion figure cited several times, though, so that gives a good idea of what happened.... LinkedIn plunges 44% Feb 5, 2016
LinkedIn's stock had its worst day ever.
Shares cratered by as much as 44% in trading Friday after the company reported a quarterly loss Thursday, with guidance that was weaker than expected.

From time to time over the past several years, with various LinkedIn acquisitions, I've noticed that the company had extremely ambitious plans. It appeared to me that they were trying to build an online cradle-to-grave human resources department, with basic training and a highly targeted ad network aimed at decision makers thrown in. The Lead Accelerator ad network plans have apparently been abandoned, which was what initially impressed me about what they were doing.
As a user, I've had mostly negative experiences with the site, but their content has gotten progressively better over the past year, I'm suspecting because professionals felt obligated to use them. Hard to say what the current revaluation will do.
