I have a system that randomly show "cards" of notes that are less than 150 words. I don't reference them often, but I often end up doing deeper analysis of information behind the notes all the time. Or just linking them into big trees of cards like a wiki. There are time when I search for information only to realize that they are already in my notes already.
