Without ads, Facebook would not be able to pay for the investments in various features like messages, video chat, etc. Plus, the goal is to create more relevant, social ads. Nobody is there yet, but that's the goal. The goal isn't to get people to click on those ads more per se, but to get people to derive more value from them (viewer value + advertiser value), a fraction of which the website can capture. Disclaimer: I was an intern on FB's ads team last summer. I truly believed my work and those of my colleagues were very important. We wanted to reinvent advertising the "Facebook way".
