QT is used for any number of reasons Ashley. When it comes specifically to discussions that turn into heated debates, well as long as they stay on topic and respectful, they don't need to be in QT really.
The hard part about a seperate debate thread is it would be all over the place on any number of subjects. The information in there might well be of great use but how would one wade through to find some specific piece of wisdom? How does a Mod or Admin know where the line is between topic, discussion or debate if we needed to move something? Debate is healthy and a wonderful part of this forum's threads, it always has been and within that debate I think we all learn.
Such as, crushed ice vs cubed ice that post would go in the debate forum.. (silly example forgive me) i was just suggesting we have forums like that on other message boards im on
Pat! Cubed all the way! How could you promote crushed ice! Heavens, I'm appalled, just appalled (and still in shock finding out it's been Ashley all along sneaking into my favorite grocery store to smoosh the grapes)! Crushed, imagine that! *faints*
