You are missing a point!
Quoting is definitely discretionary, but users or quoters should do it smart and in more-skilled quoting method to keep their threads comfortable, avoid to make their threads really annoying. I hate to say this, but when I found (by chance) threads which were quoted times to times, I did not want to read it. Those annoying threads make me feel really hard to follow the flow of ideas.
Just my opinion, so take it easy, JayJuanGee.
