I have made my facebook profile open to everyone on facebook but why is it still private?

[Peaceful]

I have found other facebook profiles open. I know that I have chosen for it to be viewable by everyone on facebook but it is not. Also, is there an option to make it private to some and open to others that are not your friends?
I have done everything that you both have stated before. I went back to do it all again. I have made it ZERO privacy on every count but still, the only thing that can be viewed is my friends. I want people that are not my friend to be able to read my wall postings and other postings on my home page. But it just won't work.
I have two facebook accounts and in one, I have searched for a guy friend I know for his account. I can see email and contact email. You can click on the picture and see his profile. When I search from my other account, it only shows email by his picture. You cannot access his profile in that one. I am computer savvy but I see no option for this.
