"i wouldn't be surprised if they actually started charging large corporations like nike for their pages usage" That's the thing, I think their valuation is based on the ton of potential revenue opportunities like that they haven't explored yet. There's a ton of companies getting value from Facebook marketing (not ads, pages and so forth), Facebook just (in theory) needs to figure out how to capture some of that value. And look at stuff like Zynga as well -- they built a billion dollar company on top of Facebook's platform, and now make up something like 10% of FB's revenues IIRC. Are there any similar untapped opportunities for the company that owns the world's social graph? I know it sounds kind of airy trying to value a company on as-yet non-existent revenue streams, but what's the chance they don't manage to find a few more Zynga-scale opportunities in the next ten years?
