Why does Post.print_author work? in order to get to the class method, shouldn't I be using Post::Post.print_author??

Because:
class << self
def print_author
puts "The author of all posts is Jimmy"
end
end
Provides context for the print_author method. It's a way of avoiding using self.method_name for every class method of self, or, in this case, Post.
