For me one of the best kept secrets of Wikipedia is the Navboxes collapsed at the bottom of every article. They are very good for getting a bird's eye view of complicated topics and especially helpful for seeing how something fits within a complex hierarchy. Some of them are like minuature works of art that I'd want to hang up on my wall one day:
I get why they have to be collapsed by default, but I use a userjs to move them to the top of the page, uncollapsed, so I can use them to navigate (I set their CSS zoom to 0.3 so they don't take up too much space)
to me, reading these overviews is a very rewarding experience, as every article title in the category gives me a rewarding rush of memories and context all related to a common theme. and if I don't know about a topic, it's an effective way to find the gaps in my knowledge. maybe it's not a traditional form of art, but I can see how it's a unique way to interact with a large domain of content.
