I’ve thought about this too – I started to think of my wiki as a textual memory palace in some way. For helping to path it out/memorize it I thought it would be fun to have kind of text adventure paths through it. I kind of did that (along with a little sketch) on the homepage. (mentioned briefly in here under the Personal textbooks? section commonplace.doubleloop.net/wikis
I also wondered if wikis then became collaborative in some way, they could become collaborative memory palaces. commonplace.doubleloop.net/20200308210932-collaborative_memory_palaces
All quite half-baked ideas at the moment but something I really like the idea of.
