Walls of text are why books pile up unread. Scrine breaks a book into the next thought, and the next, so the hardest part is putting it down.

This isn’t a substantive criticism, but one aimed at helping adoption: the word “scrine” does not feel remotely joyful to me. It seems like a combination of “scream” and “whine.” It feels sharp, in the bobo vs. kiki sense. I imagine I will be impaled on the tines of a scrine.

This seems like the very opposite of reading. How can you understand anything when your context is interrupted after a sentence or two? Flow is impossible.
Even a page flip is less disruptive than scrolling because it doesn’t use the same part of the brain.
A wall of text is much easier to read than something broken up because you can stay in flow.
