Here's my question: Say it turns out that in a year or two Facebook settles onto a good solid advertising system that makes sense to advertisers. Revenues to a sustainable $5b and keeps up a nice sweet margin of 25%-30%. Expected growth is 10% for the next few years as advertisers figure out how to use it (in my opinion this was the driver of Google's growth post IPO). That's a genuine whale. As a startup story it's massive economic success in a short period of time. Even this (hypothetical) post IPO year or two seem (to me) like a success story. But.. investors (at the present stage) are betting (according to the price) on much better results than that. 5X-10X better at least to call the investment good. I'm not saying this will happen (I dunno). I'm asking what if*. Basically the company which didn't exist a few years ago is now a huge (& good) company. Easily worth $20bn, maybe more. But investors are losing money. How bad is that? Does the company fall apart. Is the danger bad enough for managers risk everything over & over to avoid it? ^ I'm going on media reports of Mrkt Cap/Rev/Profit of $100bn/$3.7b/$1b
