The problem with this is that you don’t learn any new features that you wouldn’t have come up with on your own.
I loved reading the well-written manuals and “on-line” (integrated into the software) help of the 90s (and 80s) that explained all the concepts and features of the particular software. You’d learn a ton of new ideas and possibilities. It was really fun and exciting, and it gave you the perception of a well-designed and well thought-out whole. You built up a consistent mental model of the software, and you thus ended up with the feeling of mastery and control over the software.
Nowadays it feels more like poking the software with a stick in an attempt to build a mental model and discover its capabilities by trial and error, often remaining in doubt about the actual intent of how exactly things are supposed to work.
