It's Wiki is pretty killer.

That may not sound like much, but it's pretty awesome. I use it as a reference on a few things even when dealing with other Linux distros.

e.g. The page on SSH basically starts with how to restrict users who can log in and disabling root. https://wiki.archlinux.org/index.php/Secure_Shell

Haven't used Arch in a while - not dealt with a non-company Linux box for a while. But it remains my go-to Linux (for development purposes) for good reasons.

Seconding this: the killer app of Arch Linux is its community support.
