"It's hard to imagine the privately held company being worth nearly as much as it was a year ago."
It's hard to imagine how Facebook was EVER thought to be worth ANYTHING. Hell, I LIKE Facebook and dip into it pretty much daily, but I'm buggered if I'll give them one single penny of my hard-earned.
