Thank you for this pointer, Harold! My kind of list! I just saw Jane in Twitter (when she acknowledged your tools post) and started following her as well. I can see this will be fruitful.

I want to become more effective managing information (primarily on my personal computers) through more associative means (versus named folders within folders within folders...) so I'll work through Jane's list with this initial goal in mind. I was using mind maps for this purpose, but it became too mechanical and static.
