I wholeheartedly agree with this sentiment, despite the thoughtful responses (with which I also agree in some ways).

Writing should be clear, well-organized, and purposeful. Writing that is not, is not. Quality is self-evident.

It's not particularly worth spending a great deal of time criticizing, but it is an entirely valid point. I took very little of value from reading this in full. I say that as a product designer myself; I agree with some of the points, and a lot of what was said was correct (a lot seemed to be conjecture or just plain wrong as well...), but it just didn't come together to anything meaningful.
