I write a lot of tutorials and guides and I strongly agree and disagree with this comment at the same time.
a) Yes, the words "simply", "obviously" etc are waay overused in this kind of writing and when editing it's often simply a case of doing a find and replace to remove them all (obviously after checking each one to make sure it still makes sense)
b) 3500 words is not a lot of text. Somehow marketing people managed to convince the world that a "long form" blog post is 500 words. In reality, 2000 words is often a ballpark minimum to say something useful and interesting, and 10000 word articles are often super useful (and still not that long given how easy it is to skim over bits of text, how fast text can be produced and how lightweight text is in terms of bandwidth and storage space.)
I'm actually quite amazed, and happy, how far security has come.
