Question of the Day: How old do you think someone should be before they are allowed to create a Facebook account? Why?

I believe that anyone who knows how and is allowed to use a computer and internet at home should be allowed to have a facebook account. I believe that its only fair. Facebook is for everybody. For friends, family, associates, and even co-workers. I don't believe that there should be a age limit to a website that doesn't have an age limit itself.
