Myself being a non-vi user, I find that visudo is hard for people used to nano. Besides, use of visudo is only critical for systems where no one knows the root password (default Ubuntu for example). If you know the root password and are on a generally single user system where there is no risk that two people would be modifying the sudoers file at the same time, don't be afraid to edit /etc/sudoers with nano. If you manage to break sudo, you can always fix it with su -c "nano /etc/sudoers" and by typing the root password. -- Sébastien Leblanc
