I've been on Linux since 2000s and still maintain the view that real men log in as root on tty1. It's ironman mode, and pure joy of *nix as it was meant to be experienced. You filthy casual. /s
UNIX was designed as a multi-user system. So the joy of UNIX is using many users on one machine.
Which, incidentally, is the most pleasurable way of experiencing UNIX and UNIX-likes. (Shellboxen)
