Why aren’t my facebook friends in alphabetical order by last name?

I notice that on Facebook, all my friends are in alphabetical order by their first name and not their last name. Why is that? Most phone book directories are in alphabetical order by last name but Facebook isn’t!! I don’t even know if myspace is either!

MySpace sucks haha. But they've been arranged by their first name for years now.

To make it easier to find your friends. You call your friends by their first name, not last.
