I've heard that repeated dishwashing can cause (or hasten) the crazing that is commonly seen in the older mugs. Never tested it, but it makes sense that repeated wide temperature changes could cause superficial cracking in the glaze. Of course, I kind of like crazing in the older mugs--- I think it gives them character.
Modern glazes might be more durable than those from the past.
