One frequent mistake done on facebook by clients is creating a profile page instead of a fan page. The main conqequence is that of course you need to make friends with people for them to see your page, while fan pages are publicly visible. Of course, it was impossible to change the type of your page on facebook and you had to live with your mistake.
