Given fb's current position - would it not be incredibly stupid to NOT do everything possible to continue their growth and try to become more widespread as a necessary layer of the internet?
Assume they want to continue growing. Growing both the number of total users and the number of places they grab the users' attention (mobile is the next natural play). Of course they would continue raising money and not worry about profit margins right now as they are still driving money back into the company's growth.
There are two factors that influence your 'multiplier theory' given their advertising model. Number of users and the amount of attention you have from those users. They still have a lot of potential upward growth in both areas.
If facebook made a billionish dollars this year on ad revenue - they could double it with twice as many users. Double it again with twice as much user attention from being a core part of the mobile web. They are still growing their ad platform, so that is another multiplier.
