I usually agree with this sentiment. I have a general disdain for elaborations and novelization. Get to the point! Give me the necessary facts and make it concise!
In this case for some reason, I disagree. This post is engaging for me. I sometimes elaborate on how I came to a conclusion because that journey is equally as fascinating as the conclusion itself. While reading this authors post I was happy to see what seems like a very thorough thought process.
It was actually refreshing for me to see someone write at such length and find myself engaged.
It worked for me.
Now, putting my self in your shoes, as I have regularly had the same opinion, I have more empathy and understanding for how people consume and enjoy writing.
The world is fascinating.
If you think a bit, you'll notice that it's long but it's not padded for content length. It does not repeat the same thing 100 times with different wording. Every "bug" he talks about is somewhat different.
