one problem I notice with how they greet knights and lords in alot of fan fics not just about ASOIAF / GOT is he says my lord, he is not a lord but a knight he would say sir with his name sir jamie for example, as for Ed stark he would say lord stark or if he knew him lord eddard you would only say my lord if you are swarn to him is my point.
