I've never really understood Facebook from the business side at all. I generally like the service they offer (generally, though it is really lacking interesting and helpful aspects) but I've never understood their thinking on business moves. They've got a very popular software platform, one of the most visited sites in the world and rising, and some how 700 people can't figure out how to make a buck.

I agree with most of the other people here... Zuckerberg promises a business plan in 3 years? What the hell? I can see having your product and company out there and be selling things or providing a service and not necessary have the business plan down and taking some time to find one that really does work well, but when you have 700 people, corporate offices, and a widely popular product/service, a business plan seems to me to be something you put at the front of the line. Not: "hmm, we'll get to it later, lets just enjoy the fame!"

Most of what goes on at Facebook could be ran by 70 really good people. That's not including investors/shareholders at all. That's 70 people that are just in charge, server/network managers, system engineers, accounting (do they need one?), and marketing. It appears Facebook got the idea that it needed to have its own in-house Microsoft Research or something.
