Thank you for this explanation. I am one of those who see the comments first before going to the actual app :) One thing stood out to me in your explanation — you say “tree structure” is a natural way to organize knowledge. Why is that the case? I generally use one of the modern “tools of thought” (first Roam and now mem.ai) and in these tools, you just dump notes and add tags and and links among notes, so you have a general graph structure (from the links) overlayed with tags.
