The problem is that their business model is probably more sensitive to overall economic health than most. Premium services that are nice to have for recruiting might be some of the first things to get cut from customers' budgets in a downturn when they're not hiring as much. I suspect that investors are jittery about the economy overall and think LinkedIn might be in for a slow couple of years if the economy stagnates. They're repricing the stock to reflect a slower growth trajectory.
