This is extremely cool. I’m kinda busy so will just paste the header from the author’s site:
TiddlyWiki - a reusable non-linear personal web notebook
TiddlyWiki, an experimental MicroContent WikiWikiWeb built by JeremyRuston. It’s written in HTML, CSS and JavaScript to run on any modern browser without needing any ServerSide logic. It allows anyone to create personal SelfContained hypertext documents that can be posted to any web server, sent by email or kept on a USB thumb drive to make a WikiOnAStick.
Although I can’t think of a place where I’d use it on the internet, I like the idea of putting it on a memory card for a personal note-taking system.
