WikiNotes – Organize Your Brain
http://wikinotes.mug-linz.at/

WikiNotes is a free application for OS X 10.4 (Tiger) that helps you to organize your brain and be productive without a hassle. Just start writing and then whenever you feel the need to break off into a new thought, create a link with the corresponding CamelCase word. Then, just like WikiWikiWeb, you get a new document with a single click with many features. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
