I get e-mailed when someone replies to a thread. I set it up so that I automatically subscribe to any thread I comment on and get notified when someone comments on subscribed threads. Quotes are a subset of replies. I am not sure that a specific Quote e-mail you get you anything better. If you quote me on this post, I will get notified or if you don't quote me by say, "Newride, you are full of it how do you respond to X". I get notified also.
Also, to me stromtrooper isn't the sort of thing warrants my dropping everything I am doing to reply immediately. Anything on stromtrooper can probably wait until I am on stromtrooper again. If you really need my immediate response you would probably send me a message asking for my real phone number or e-mail.
