James, I’ve been watching a few people use public-facing TiddlyWikis for “hyperchat
of them also has it set up with Webmention
functionality so that other sites can send it notifications (though they’re not yet displaying them). To me this looks like the beginning of a different sort of social network and online communication.
I ran across an example yesterday of someone using a private local TiddlyWiki as a static site web generator, which is quite different from people hosting them directly on web servers.
I’m interested in off-label use cases for wikis (particularly in the vein of commonplace books), so do let us know when your article comes out.
