Author here. I appreciate both your perspectives; not all writing can be for everyone, of course. As it happens I'm in the middle of writing a very long essay in a much more restrained style and decided to kick out this as a fun blog post to take a break. It's nice to see some people are enjoying it. At the same time I understand why you may not, as well.
Truthfully, the whole post is really just two points: think hard about your business, then be honest with what you know. But sometimes writing about antelopes is fun too.
