Hm? I've never really thought of it. To me it always just seemed like kind of the norm here, and one that for my own personal reasons I wasn't willing to follow.
I've had plenty of people suggest that I cut down, and separate my pages because having it all in one really long episode can "overwhelm" (for lack of a better term) readers, and having them separated would just make things much easier.
The reason I never did so is because I just like having each episode organized AS an episode, and it's not really something I'm willing to break.
