A :popcorn smiley would allow us to indicate that we will be lurking on a thread and watching the flame-carnage unfold. For instance, the classic Tyrannis vs. LLogan smackdown, those two just never stop. Also, a flamewar recording option would be beautiful (in order to preserve the hilarity for future generations).
A dancing lock would also just tickle many pink, in order to remove the old, worn out IN.
