The purpose of his blog is to create hyperbole in the opposite direction of the current prevailing ideologies.

So there is a lot of crazy stuff in it. But there is a lot of information and perspectives that can be found nowhere else, and if you read them and incorporate them into your world views, you will have a more accurate picture of current reality, and you will make better predictions about world events.
I do agree with the long-winded part. Some people like his whimsical, sci-fi jargon infused, verbose writing style, others cannot stand it. That is a matter of taste.
