I agree, the ease of installation of GOS and it getting exponentially more known to the broader public, brings many people here which then, like u, (and me) get interested in obtaining more knowledge regarding this security/privacy spectrum. A gateway if u will.
I tend to scroll this forum before bedtime or when i have a smoke, and sometimes i come across some valuable subject i wasn't really aware of, and then research that specific subject more broadly.
Following GOS on mastodon brought many of those valuable subjects up aswell.
So as a recommendation, i would advise u to do just that, scroll this forum once in a while, and dive deeper in subjects u come across, if they are of any interest to u.
It's very hard to give specific directions, as this spectrum is really really broad and deep. Which then again makes me have massive respect for this, well-proven, project.
