Wish I could say the same, so far Linux knowledge seems to have done very little for me as far as employment goes. I have used it at work before but normally it isn't something anyone else seems to care about. At least my limited knowledge of Windows hasn't been too significant of a problem so far either.

I've been running some Linux servers for fun, at my last job we also had quite a few. The only admin quit, no documentation. Guess who got a big salary increase because he was the only one with the knowledge required to keep this shitshow running? Yep, that's me.

Thanks to past me for installing every distro under the sun and sinking years into the commandline, shell scripting, web and mail servers just for the thrill. Linux is awesome.

Ymmv depending on where you are. I was happily employed in the Unix space until I moved to Seattle.
