Was first thinking (hoping) this was a decision tree what to read for all research papers of the last 30 years. Would be a gigantic tree but immensely cool to traverse such a tree based on decisions (questions) in the root and child nodes until you reach a collection of leaf nodes with papers to read. Parked that idea for later :).
This is also nice but not for me personally as the topic is not in my direct interest for now.
Thanks!
