Lila any good solution design, we should start with the problem, but the author skips right over that part: > [The superscript number] indicates to you that I, the writer, have something more to say on this topic. Not really, though? Notes range from citations to parentheticals. “Having more to say” would be included in the main text I’d think. The point of notes is that you don’t “have more to say” on the main topic, but you have this other information that some readers might find useful. I do agree that there is no need to get hung up on solutions used in print (footnotes and endnotes) for online material.
