When I was the editor in chief of the Cloudflare blog we had a very, very strong mission to "educate, educate, educate" our readers. That often meant including details that someone versed in the field would skip over or find too basic. After all, we were writing for a general technical audience interested in learning about a topic.

So, its natural that some readers would find parts over-explanatory but the hope was that they could read past those bits and the less educated reader would come away having learnt something new.
