Some of it is good and some of it is bad.
For instance it basically says that installing arch manually to learn is pointless and you should spend that time taking an operating systems class. This is confusing two completely different kinds of knowledge as well as time investments 2 or 3 orders of magnitude apart.
The site is also presenting opinions but using language that makes it sound like it is presenting facts.
Overall, I don't think it's a great site. It basically says "there are many differing opinions on various topics, but mine are the correct ones and you should treat me as an authority because I made a website."
Not a fan/10
