I’ve tripped on a fun use of contextual backlinks in my cooking practice. After I get back from the farmer’s market each week, I plan out that week’s meals, linking to empty notes for key ingredients. Over time, each ingredient grows a useful index of preparations via backlinks. 
It’s funny—I could get the same result by just searching my cooking notes for “peas,” but this feels meaningfully different in a way I don’t understand. One factor is object permanence: because peas have a concrete “place,” I add general notes on technique to that note over time.
Another interesting advantage of object permanence is that it enables browsing. Searching depends on me having a specific query in mind, but with this approach, I can browse all notes tagged “#ingredient” (or whatever) and see what inspires me. notes.andymatuschak.org/z2newCwFfd6iZF…
