Amazing blog! However, I'd like to point out a potential improvement in the 'download Arch' part of this blog. The thing is that a lot of ISP's don't allow torrents at all, so the user may need to be able to download the file directly.
All the direct download links are located right below the check-sum portion of archlinux.org/download but they may not be obvious to a first time visitor.
I think it's important to mention in your blog that the user can also download the ISO directly using the mirrors if they can't use torrents.
