Just a quick note to document the fact that I've been finding TiddlyWiki very useful. I'm using it as a personal notebook to organise, correlate, and hyperlink various bits of text, todo lists, etc. Previously I used to store everything in text files in subdirectories off my home directory, but the following features set TiddlyWiki apart from text-files-on-the-desktop approach. The first two are the 'killer app' features for me:
- Wiki-like hyperlinks to link your various notes together
- Excellent search functionality
- Completely self contained application (a single html file)
- Saves to your desktop/hard drive or usb stick
- Versioned (each time you save it makes a backup in a backup directory)
- Zero install (download the file and start using)
- Optionally publishable onto the web
- Loads of plugins
Here is a nice example of a TiddlyWiki that contains hundreds of Haiku from centuries past, translated into english: Japanese Haiku.
