    def method1
    end

    def method2
    end

end

class Blah

  private

  def method1
  end

  def method2
  end

# vs.

class Blah

  def public_method
  end

private

  def method1
  end

  def method2
  end

end

I've always used 1 but at my current job they use 2 so I've switched to that for the sake of consistency. I don't feel strongly but prefer 1.

However, I really dislike 3 as it visually interrupts the scope of the class.
