Primarily, it's about efficiency, and being able to work on the remaining (and likely the most difficult parts) of the story without distractions, or the added challenge of having to crank out the next serial update as fast as possible, which means I always have to stay totally linear with the work. This way I can produce the rest of it more comprehensively, prepare animation assets in advance, do more stuff in parallel, etc. It will go faster. And ultimately, I think it'll read better as one thing, rather than as a sequence tortuously spread out over time, as has been the norm for years. I think it's close enough to the end now to safely retire Homestuck as a serial reading experience. There's nothing to be gained from that presentation anymore, in my view. It's just time to bear down and get it done.
