Federated Wiki
MassiveWiki links A Markdown-based wiki; the Obsidian Project is a client. Obsidian felt awkward at out-of-box; maybe a video intro would be more convincing? Update on Obsidian: a useful linked notes tool for the Writing the Other workshop, Crafting Diverse Relationships.
Personal wiki for Zettelkasten or organizing learning, maybe Gollum Wiki (also Markdown-based). TiddlyWiki is yet lively as an alternative personal wiki.
Computational Notebooks, including Jupyter, Observable, Glamorous Toolkit.
Literate programming more generally
Navigable information spaces
Plugin based computing environments (shallowly, as FedWiki, vs. Eclipse)
