I have really found TiddlyWiki to be of great help. I have been using them on a usb memory stick for a couple months now and have grown to like it for capturing data, links and other info.
My favorite things about the TiddlyWiki are:
- Its all in one html file
- Searching is fast
- Composing a note is simple
- Notes can have references
- this makes for an option of opening all of the relative notes at one time (very cool)
- linking notes together with out having to type specific info into the note itself
- Timeline shows what you have been working on recently
- Orphans show unused notes
I am sure there are plenty more benefits to using the TiddleWiki system. If you have any, please add them to the comments!
