From http://thoughtstream.org : ThoughtStream is a program that allows you to store information and organize it the way your mind works - by associations or links between ideas.

It's sort of like a Wiki, although more structured. Some things that I hope to do with this structure that can't be done in a Wiki:

The desktop version of ThoughtStream is written in Python, using wxPython for the GUI. I'd also like to do a web-based version, so I may be borrowing some code and/or ideas from ZWiki
