Totally agree. Files&Folders are almost omnipresent, which is why people get used to it so much that it starts to shape how they think about structuring things.

Totally agree. Files&Folders are almost omnipresent, which is why people get used to it so much that it starts to shape how they think about structuring things. But if you take a step back, they are actually not the right abstraction for most things. In this case, a tagging system would serve the purpose much better. Unfortunately, tooling that deals with files&folders and text is very mature and it will be hard to extend or even replace it.
