From a Digital Ocean article on editing sudoers:

>Traditionally, visudo opens the /etc/sudoers file with the "vi" text editor. Ubuntu, however, has configured visudo to use the "nano" text editor instead.

I know `vi` isn't particularly accessible, and there were more than a few times `vi` popped up when I was writing a usenet post or composing an email *years* ago and I had to ask how to write and quit, but isn't making nano the default for a command named `visudo` taking things a little too far? I mean, if you can't google `:wq!` and you're editing sudoers, well, I think your box is in trouble.
