Facebook finally filed to raise $5 billion in an initial public offering with the U.S. Securities and Exchange Commission late Wednesday afternoon. The social network, which began as a "decidedly private Harvard hangout, has begun the process of going absolutely, totally, unabashedly public," says John C. Abell at Reuters. The SEC-1 filing contains some startling revelations about the company, from its commitment to a "hacker manifesto" (the belief "that something can always be better and that nothing is ever complete") to the gargantuan paydays for a number of investors. Here's a look at Facebook's filing, by the numbers:
