It goes two ways. There's e.g. a lot of talk about 'use your own damn systems and you will understand us and would've never made this monstrosity'. Which... just isn't (consistently) feasible. I use SE in my spare time because it's something fun to do besides work. And all I know now, took me 4 years or so of doing that, to gather.
If SE *is* your job, it makes sense you'd be doing something else in your spare time, and you can't be using the platform as much as some power users do.
