You're probably right, I was thinking back to my first real Linux learning curve with Slackware around 2000-2001. I dived in head-first and I'm glad I did, what I learned doing that built a foundation that has served me well.
Yeah, and you did that because you had to back then. :)
Thinking more about my post, I left out the option of just staying with Linux Mint after a noob gains experience.
Not that I'm anything like a role model, but it's my default personal distro, because it doesn't try to be the main focus of my computer experience, it just gets out of the way lets me focus on the work.
Mint is a great OS, I used it off and on for several years. I enjoy getting my hands dirty and I like fine-grained control over my OS though, so I've always gravitated back to Slackware long-term. Not to drag out the dreaded car-computer analogy, but it's why I keep my old 1982 farm truck instead of buying a more modern work truck; it's simple, I know it inside and out, and it runs just the way I want it to.
But you can't go wrong with Mint as a "get out of my way" OS, as you said.
