And yet, 50% down, its still over priced!

This is a 10-15 billion company at best.

Much like Zynga its the lower ranked staff that will suffer most from this =(

I won't be surprised that FB be under $5 when the common employees finally get's their turn to sell (after all the VCs and founders who get's to sell first).

Sounds about right -- that would put their P/E ratio somewhere around 22, which seems a hell of a lot more in touch with reality than the 111 that it's at right now (or the 200+ that the stock debuted at).
