Alrighty, old Linux user from the earliest of days.
It was fun, really great to have one-on-one with Linus when Lilo gave issues with the graphic card and the screen kept blank during booting.
It was new, few fellow students where interested, but the few that did, all have serious jobs in IT right know.
Probably the mindset and the drive to test out new stuff, combined with the power Linux gave.

Great for small and large scale networks, add devices by entering ip and snmp credentials and all done.
Add alerting if that’s your cup of tea.
