Creating a "signpost user interface" can help to uncover directions to take in digital contexts as out of sight is out of mind. Having things sit in your way within one's note taking workflow can remind them to either link things, or move in particular directions for discovering new avenues of thought.
Example: it would be interesting if Jerry's The Brain would have links directly to material in Flancian's Agora to remind him to search or find relevant material there. This could help with combinatorial creativity with inputs from others, though it needs to be narrow so as not to result in rabbit holes which draw away attention.
