@b0rk I'm the kind of person who enjoyed reading man pages for leisure.
I read through the entirety of the rsync man page to compose my own favourite rsync invocation once.
The only tools where I resort to web search are shells, because their man pages are really hard to navigate (finding documentation for `read` in the bash man page is ... a nightmare).
Web search is often imprecise and as you note, has gotten so much worse that I am glad I never fully relied on it.
