"the author does not think nested hierarchies are difficult. If he added "for nerds", I would agree with him." Imagine you badly need to go to the bathroom, and the only building nearby is a huge hospital... will all the complexity hidden away in the various sections, rooms, and the patients themselves, delay your quest for the toilet even one second? Also, the brain can only keep a bunch of things in mind at a time,no matter how they're presented. When complexity crosses the threshold, we group stuff together. And we also do this with a flat list, in some way or another. Reality and our concept of it is very deeply nested, but since we only handle a bunch of abstractions at the same time, that's fine. With folders, you have something that is explorable. You can still search, but if you don't have folders to begin with, you can only search -- and anything you don't think of searching for is either lost forever, or can be seen only as part of a huuuuuge list. IMHO it's regression alright, no two ways about it. |
