“It’s like a hypertext card index system from the future” -Jeremy Ruston, in the TiddlyWiki intro video
Everything in TiddlyWiki is a small piece, a tiddler — a British word for a small fish — which you can stack, arrange, and link however you like. Tiddlers are individual units that you can incorporate into larger tiddlers through a process called “transclusion.” To have a tiddler all you need is a title. This is very similar to Scalar CMS where all content is equal, and can be linked or embedded in each other to tell both linear and nonlinear stories. However, TiddlyWiki is not as pretty and is focused more on note-taking and information management than presentation.
There are a lot of options for customization, as well as an active community that keeps the project alive and adds new customization options for different purposes (such as for writing a thesis). There is a WYSIWYG editor and formatting options, though you will still need to become familiar with the WikiText language in order to use more interesting formatting and customization. The WikiText language is similar to Markdown. There is also a plugin that will let you write your tiddlers in Markdown if you are more familiar and comfortable with that. You can add images and scribble all over them, as well as save links to websites with a download and some difficulty. TiddlyWiki includes search functionality and tagging, which is especially useful, as you can click on a tag you get a list of pages that have that tag. There are encryption plugins, which I have not tested, to create password-protected tiddlers and offer some basic security (though neither I nor the creators of TiddlyWiki endorse putting sensitive information on one of these sites).
Setting up where your files save so you can find them again is probably the hardest part of setting up a TiddlyWiki. It creates one HTML file that you update as you save. If you’re using Firefox and using the Firefox plugin I recommend downloading an empty wiki and copying it from your Downloads and pasting it to your G:Drive or another place where files aren’t deleted automatically. After, you can click on the cat icon and set it to automatically save your changes to your file on the Desktop.
Note: Don’t save things to the Desktop on Scholarly Commons computers long-term, as files are routinely erased.
