A friend just gave me a link to a piece of software called TiddlyWiki. Besides the neat name, it is actually a ridiculously useful piece of software. Its a Wiki inside of an HTML file. Seriously. So you can bring a wiki around with you anywhere that you can edit at any time on any (modern) browser without requiring server software.
Anyways, its way cool, and I’ve already thought of a million different uses for it… though really, you have to use it to understand why its so freaking sweet. Go there. Now.
