Its great to see so many employees on that list. No one can say the early-birds didn't get their share.
Zuckerberg, Moskovitz, Saverin, Hughes were all founders.
The rest were C-level executives, most of which were brought on later through connections.
The only real employee is Callahan, which owns .08% of the company...and it's very telling that there are no other rank and file employees on the list.
And .08% is peanuts, if you were a programmer in a company that got bought for 100 million, your stake would get you a grand total of $80,000.
