@JeremyCherfas Oh yes. Doing it with paper sounds tiresome as heck.
The idea I saw in ZK that I haven’t seen in something as now-common as a wiki is to add explicit backlinks. Normally, wiki-linking is one-way, and you have to go out of your way to see “what links here”. Having that smack you in the face would hugely increase the amount of web-walking you could do & felicitous discoveries.
Good call on explaining the link. Often, link explanations take the form of transition text or make up the hyperlink anchor itself. Unexplained “see also” lists do show up depressingly often still, though.
