You are absolutely right. I do see well targeted ads based on my preferences, but I'm on facebook from september to may at school when I'm broke. In the summer when I'm making solid money I don't go on facebook and thus don't see their ads. Maybe when we all graduate from college and have more money their user base will be more valuable.
