I've created a page for my Debian TiddlyWiki, which I've built up since switching to Debian.
The skeleton *.deb file linked to on that page is discussed in the TiddlyWiki.
A TiddlyWiki is a 1-page wiki with a built-in editor.
Download an empty TiddlyWiki from this page.
Lastly, a warning: Avoid Google's chrome browser (yes, I know it's damn fast) until you've understood the implications of these notes.
Basically, chrome 'rectifies' your HTML by upper-casing it, so the TiddlyWiki's editor stops working.
