I followed discussions of the FB float from the start. Didn't they start talking about it a couple of years before the event? I thought it was a scam, given the owner and Goldman Sachs being involved. It was obvious to me that Zukers would set the price way above value. Now all confidence has gone from the issue. There are no fundamentals. So how to tell the natural price level? Putting money in is just gambling.
Probably best to put your money into Monsanto. The evil bastards are taking over the food supply of the planet. Personally, I have gold & silver (but not paper).
