Good to hear. Nano's up-front display of the core key combinations has been a source of relief for people getting dropped into a terminal editor for ages. Wish more distributions would set nano as the default $EDITOR instead of vim.
Oh my god yes. nano, moe, and JOE are more lightweight than vim, and have better ergonomics. I can understand setting $EDITOR to nvi, mg, or similar, but setting it to vim is ridiculous: Vim is in Emacs's weight class.
The worst is when someone who's never used Vi before gets thrown in there after running, eg, 'git commit'. Can't Google how to quit because they don't even know the name of the program!
