I always wonder this as well, and, in my opinion, no there is never more to it than that. Interlinking notes with hyperlinks is a huge convenience that plays a role in all these "new" methods but academics (and others, of course) have always had manual systems for this.

What I will say is I am in favor of anything that encourages people to write and create versus just consuming content. If fiddling with a new system encourages this, that is great.

Data stored in files within a hierarchy of folders. It's the hot new thing!
