You really don't know what you're talking about. LNKD was not in S&P 500, "only" 8% off consensus earnings is not a small number, P/E multiples are nowhere what they were in 2000, there's been relatively little IPO activity. It's a different world. It may be a tough market but there's no basis for (most of) the numbers you are throwing around.

I could definitely see a decline in engineer salary, which could be significant in certain markets. But who knows.
