Interesting idea. If your analytics reports don't cause you to change course, there is no reason to collect them in the first place.

Still, it's hard to believe that analytics add zero value to an aspiring self-publisher. What about simple things, such as knowing which posts get the most traction, and so may be more likely to appeal to someone buying a book or course. That information can be quite counterintuitive.
