It's always good to give back to the community. I have a couple of suggestions...
What if the distro you pick doesn't have a GUI installation like Fedora? You have to everything you discuss from the command line. You may want to preface your article with that disclaimer.
The swap space is typically function of your RAM capacity. That is, a rule of thumb that I've always used is swap size >= RAM capacity. It could be a stupid rule of thumb, but it's what I learned.
Anyway, good job, good luck, and good night.
