I love nano. I used to do tech support for a Linux-based content management system (before SAaS take took off).. The customer sysadmins were sometimes whichever engineer was volun-told to do it, so competency varied wildly.

I helped mostly with installs. This might be the poor newbie sysadmin's first time on the command line. Nano was my go-to suggestion for editing config files--all the commands are right there! Much less intimidating than vi or emacs for a newbie.
