Vim should be learned by blood sweat and tears
Or you could just curse the random box you ssh into for not having nano
or learned via nethack.
To be honest, I know vi and emacs, and curse fresh Linux installs for having some weird editor with completely foreign control keys. :) Dunno if it's nano or something else, but it's mildly annoying to me. I tend to just uninstall it rather than muck around with the "alternatives" system.
Default editor is mg, which is basically a micro-emacs reincarnation
