Facebook IPO, Who owns Facebook and more

So it looks like Facebook is filing papers today for an IPO of $5 billion. That is half of what was rumored and almost certainly keeps the little guy (those with less than 100K to invest) from acquiring any of that IPO stock. I am thinking that the reason that Facebook reduced their IPO is because most IPOs rise so fast and then fall. Even immediately following Google's IPO the performance was far from what was expected, though those that still hold it today have enjoyed a 500% increase in value. I'm not a financial expert but it seems that perhaps Facebook is gearing itself up for a second public offering building on their strong first offering.

So who really owns Facebook? Here's a very interesting chart that shows where the money is.  There are a couple of interesting entries, Goldman Sachs who last year raised $500 million for Facebook and Bono (yep, same one).
