For my part, I can't stand people quoting an entire post, just to add a two word reply at the bottom. With regards quoting a section of someone's post, I don't see the problem, so long as you're not intentionally putting it out of context. If a poster has written a 2000 word post, and then there are five posts following it, I will often quote a section of their post in order to avoid confusion as to what part of a discussion I am addressing. Don't really see how anyone can lose sleep over such a practice. I agree that to take every point made, and answer them individually, is a bit pathetic, and self involved. However, I see no problem with addressing a couple of points seperately, if you feel strongly enough about a couple of points to bother.
