Explore Wikipedia Like a Windows XP Desktop

While many did pick up on the idea, where were the shortcomings? Were the early graphics not enough to build the mental link. Was it the common grid view of icons. Was it the icon being an abstract thing you needed to open to see the contents instead of looking at it directly (as previews on the icon which came later), was it things opening in separate windows. It's not as though other more visually 'rich' methods to show a file system such as 3D or animated took off.

There's also the modern version that gets brought up occasionally where people who are using devices with mobile instead of desktop OSes apparently don't know how to work with file systems to manage data, and presumably they'd have even less exposure to the physical paper concept that inspired it.

Once you understand how that works, then additionally understanding the new/save/open buttons is trivial, but if you started with the new/save/open buttons you might not get how they work because you'd have to lose your existing wrong understanding. Learning is path-dependent.

For example, https://commons.wikimedia.org/wiki/Category:Paintings_of_cas... contains the subcategories "Paintings of castles by country" (nested hierarchy), "Frescos of castles" (a medium), "Paintings of Château de Chillon" (a subject), and "Young Knight in a Landscape by Carpaccio" (multiple views onto a specific item). Each item may appear in multiple subcategories. As far as I can tell, the UI won't let you search for frescos of Italian castles (unless somebody's made a subcategory for that), or view all paintings of castles regardless of their subcategory.

I'm not very fond of this approach. I'd prefer for each item to have an unstructured set of tags ("fresco", "depiction of a castle", "depiction of Italy"), with automatic derivation of parent tags ("fresco" implies "painting") and the option to search by multiple tags. It should be possible to automatically discover tags which best refine a search, so that the UI can still suggest them to the user, as it does today.

Since this is so terribly impossible most systems almost immediately make it possible for things to show up in more than one place, which means it's actually hierarchial tagging, whether or not the organizer(s) realize it.

You could also make a distinction based on how many tags things end up with; if it's almost always one, you could call it a nested hierachy with some exceptions, but if it's almost always more than one, and often much, much more than one, it's a tagging system. Even by that criterion that creates a spectrum rather than a binary distinction, Wikipedia is very much organized by tags and not hierarchies. I don't know what the average is but every Wikipedia page I've ever looked at the tags for has quite a few.

The little arrows next to the subcategories can be clicked to open up trees, so you have hierarchical data in there as well. Try click open eg Classes of Computers (With 41 direct subcategories, and 91 pages directly in the top level category, that's a big tree!)

Categories are criminally under-used.

> After several hours and several drug injections, Jackson was still unable to fall asleep, and, according to Murray, was repeatedly asking him for "milk", a nickname for the powerful surgical general anesthetic propofol, which Jackson had used in the past as a sleep aid. At 10:40 a.m., with Jackson still not asleep, Murray relented to his requests and injected him with 25 milligrams of propofol diluted with lidocaine. With Jackson finally asleep, Murray testified that he left his bedside to go to the bathroom, and after returning two minutes later, discovered that Jackson was not breathing and had a weak pulse.

Generally you can delete your comment if its relatively soon after you posted it and nobody replied.
