A couple of us did, except we spelled it correctly :)

'&>/dev/null' is a bashism for '>/dev/null 2>&1'. There's nothing wrong
with it for bash scripting, but I find the latter to be easier to read,
far more common and more portable, so that's what I use for teaching and
giving answers on mailing lists.

In a bash only environment, either is fine, but when working with other
Bourne shell derivatives your syntax might not work. It might work in
zsh, but I'm pretty certain it isn't allowed in POSIX shell or ksh and it
definitely isn't in the original Bourne shell.

A really cool feature of a good toolset is there is more than one way to
do it :).

ciao,
