Of course money is important to Facebook. How does Facebook make money? Have anyone here, personally, paid any money to Facebook. They have huge storage, Internet connectivity, management and development overheads... where does the money for this come from?
- The (information stealing) apps and the cuts on the micro-payments within these.
- Advertising. This is very low income however when scaled out massively can still produce a good return, however untargetted advertising is nearly worthless.
- Profiling. Profiling trends in content and topics to sell to those who are interested. Ideally entirely anonymous, however then there's the temptation to link this to the advertising and feedback loops become possible.
