[sudo-users] visudo

[Micha]

Hi,

i'm maintaining a small mixed homenet where i am the very only
one with access to router or the server box. This is no production 
system, only private office users with some centralized tasks.

There's a question i have for some years now, and can't figure
it out. I use to do administration as root, and did edit the sudoers
file with emacs, nano, and midnight commander with no problems.
Can you tell me why should i use visudo nonetheless ?
Noone else can modify /etc/sudoers, so parallel access is not possible.

tia,
