No kidding. For starters, pre-prospectus, even, FB said flat out they are turning a lot of focus to the emerging mobile market. And that pretty much a known fact that traditional advertising revenues -do not work- on mobile platforms. Translation? Less revenues. And Facebook is fine with that. Money is a positive side effect of being a household word. As long as they keep getting enough to keep doing what they want to do (be a part of every person's daily life, and reflect glory on Zuck), investors don't matter.
