For my own communications, I tend to mull things over before responding in any way, and answer most of my own questions myself, rather than look outward for answers. Mileage varies, but a few really good points have been brought up. The sheer numbers of subs v. Dom/mes, and similarly the numbers of especially female subs v. any Dom/mes, as well as the generally laconic nature of male/masculine communications, all probably have something to do with the balance of topics taking place.
