Maybe it is a WSM thing but I fail to see how. Hopefully someone will enlighten us. Keep Smokin!
Part of it is that when you stir charcoal after it has been burning for a long time it is fragile and you risk breaking it up and having it fall out of your basket/grate and into the ash which extinguishes it. Also when you stir it it lets more air hit the hot part which flares the heat and burns the fuel faster... so if your temps are doing OK best not to mess with it at that point. Finally as stated above stirring runs the risk of ash getting on the food.
I only stir when I absolutely have to and as gently as possible.
