Sorry, but installing arch linux doesn't mean you are some computer master. You are just following instruction on a wiki. Anyone could install arch linux if felt like, and wanted to put some time into it.
Some people make arch linux their personality especially the forum.
It's a highly customizable rolling release distro, but mostly the Arch User Repository!
I think there have been significant improvements on the installation too, pacstrap already does a bunch of heavy lifting for you AND their own install script now works sometimes!
