A fantastic example of an extensive mind map from Jerry Michalski using The Brain.

There are lots of interesting links and resources, but on the whole

How many of the nodes actually have specific notes, explicit ideas, annotations, or excerpts within them?

Without these, it's an interesting map and provides some broad context, but removes local specific context of who Jerry is and how he explicitly thinks. One can review the overarching parts to extract what his biases may be based on availability heuristics, but in areas of conflicting ideas which have relatively equal numbers of links within a particular area, one may not be able to discern arguments from each other.

Still a fascinating start and something not commonly seen in the broader literature.

I'll also note that even in a small sample of one video call with Jerry sharing his screen while we talked about a broad sub-topic it's interesting to see his prior contexts as we conversed. I've only ever had similar experiences with Bill Seitz who regularly drops links to his wiki pages in this sort of way or Kevin Marks (usually in text chat contexts and less frequently in video calls/conversations) who drops links to his extensive blogging history which also serves to add his prior thoughts and contextualizations.
