Ran across this; someone seeking a web-place for easy access / personal notes available via any old PC-thing.

TiddlyWiki is a single html file which has all the characteristics of a wiki - including all of the content, the functionality (including editing, saving, tagging and searching) and the style sheet. Because it's a single file, it's very portable - you can email it, put it on a web server or share it via a USB stick.

Seemed neat, but what do I know.
