The information delivered is the author's philosophy on website design and implementation complexity.
I can easily tell that the author does not approve of overly complex websites, and thinks they lead to poor experiences for the developer and user.
Contrast this with a website for some hot new web 3.0 buzzthing, where "what is this thing" is not answered in lieu of presenting a shitload of "why we/this thing is so great". An example of this is npmjs.com. Nowhere does it actually state "this is a package manager for javascript", if you didn't already know it.
