Well hello there! It's always refreshing to see the actual person behind the nickname.
GNU must mean you are a computer geek?
I am, pretty much a jack of all trades. I am the "Anything but Windows" specialist at my employer, so if a client is running mac, linux, unix... I'm the guy that goes out to fix the problem. I also have Microsoft credentials... but as you can tell by my name, I've been a Linux user for 10+ years... at least until I got my mac (I still use linux for menial tasks at home with a server-type box, just prefer not having to deal with deps and such with linux desktops).
Ever use Arch Linux?
Nope - was a fan of Gentoo but the system lends itself to dependency hell eventually so my file server is Debian. I have VM's of Ubuntu on my macbook and a spare HDD with Ubuntu for my work laptop.
The rest of my house is mac or windows.
