I agree with this. Left hand signal for right turn looks silly, and most drivers will just think you are giving them the finger, or waving to a friend, or something.
I'll use the right arm signal if someone is waiting to turn left and I am turning right. That and lane changes are the only things I ever bother signalling for.
