TiddlyWiki

TiddlyWiki is a very cool, reusable and simple wiki-style webpage. It’s a tiny download of a page that, suing some funky javascript, allows you to create a simple page in seconds which is instantly editable from anywhere at any time. You can keep it on a usb stick as a to-do list or stick it on a server/webspace for a quick site that you can allow anyone to alter (or you can limit permissions if you wish). With the addition of some plugins you can expand the capabilities with little effort – there are tons of plugins covering everything from inbuilt media players to full databases and calendars.
