That doesn't seem like a crash though; I'd wager the investor class and the general populace are quite disjoint sets, e.g. there's not a mass of pension funds involved in IT venture capital. What we might see is a "return to senses" and a shortfall of capital for a while, but not a crash.
I've been expecting that for a while. Too many startups have crazy valuations, but too many seem to make good money for me to think all the investment will dry up for 5 years or anything like it.
