As I was reading the "Do you dump your ash..." thread, I noticed a couple of guys referencing stiring the contents of their bowl after they've smoked down pretty low. I didn't want to polute that thread asking a tangential question. Is this common? Doesn't it mix your ash with your unsmoked tobacco rendering a less than pleasant flavor? I could see a benefit in helping to dry the tobacco that is at the bottom that tends to get overly moist.
