What does your last paragraph mean? Facebook already has more mobile users than web, no? And their mobile revenue is what is giving them most of their valuation. Or do you mean from the get go FB is something people are used to just from phones? If so my apologies. That does make some sense and could be true. Probably is for a lot of growing nations and economies like Africa and Asia.
