I was looking for some info on mind mapping software this past week (preferably open source), and I found an article that references me of all people.  The article was in the American Law Librarian Association’s Comptuer SIS magazine.  You can see it here. The article in question starts on page 13. From the beginning of the article by Eric W. Kistler of Ehrhorn Law Library at Liberty University School of Law in Lynchburg, Virginia:

Back in October, Rich McCue, from the University of Victoria, posted to Teknoids
a list of his favorite Open Source software packages for law students. I became
intrigued by an item near the end of his list called “FreeMind.” In Rich’s words,
FreeMind “is a mind mapping software that is great for brain storming, and
organizing projects, or your thoughts . . . Give it a try, it is a wonderful
product.”

The e-mail Eric references is here.
