The market and the economy are doing well. Facebook isn't though. Facebook's big market appeal was the fact they had all this private information on millions of people to sell to advertisers. Then there were all these people outraged over the use of their voluntarily submitted data for a FREE service. Go figure. FB handled the event poorly. So you are right in that it is a predictable crash for facebook stock.
And, never mind it was originally a DARPA project. When FB came on the scene, the DARPA project FB is based on closed up.
