The question Might more conlangers like writing in knots? is well-researched and interesting, but by the author's own admission isn't really a question that requires an answer. Do we want to allow this sort of rhetorical question on Constructed Languages SE?
I agree that this question is ill-posed as it stands, but I also think that it is salvageable. It can be reformulated, e.g., in the following way:
Q: What are resources for conlangers designing a knot writing?
(Add a little of explanation to the question title, e.g., the first paragraph of the original question, and repeat the question.)
A: (Everything starting from "I made one such conscript")
Self-answering ones own question is 100% OK, as long as question and answer contribute something to this site. And more answers may come in.
