Just two things to think about today.

What has the PKM/Zettelkasten movement produced?

Excellent article questioning what the PKM movement and tools have produced. This point struck me hard.

There's a whole subgenre of books about PKM and Zettelkasten, catalogued in this Obsidian forum thread. Ahrens, Forte, Kadavy, Scheper, and others, each producing a book whose primary subject is how to take notes, rather than a book that uses notes to say something new or useful about the world. Tiago Forte claims over 20,000 people have taken his course and 100,000+ copies of his book have sold. This is the actual documented output of the "Second Brain" movement: a course business, not a body of external work produced using the method.

I intended to write a book, and keep not getting around to it. I had some courses on Obsidian and taking notes, so I guess I'd have to say that most of what my notes in Obsidian produced, were more notes about PKM and Obsidian not new interesting thoughts about the topics I thought I was reasearching.

Now, can I change that or is an inherent flaw in the system that it will produce little new work and much thought about the system?

No one wants your newsletter

Nobody asked you to write a newsletter; and as a baseline, nobody gives a shit whether you do or you don’t.

But in my fairly qualified opinion, you should go ahead and write on anyway. Write it how you want, write it where you want, and publish it no matter how much it might feel like screaming into the void.

Because the best newsletters in the world were written by folks with a bone to pick and an itch to scratch, who had no actual evidence that the world wanted it. - Nobody Wants Your Newsletter

I like this advice, and by many metrics my newsletter isn't succesful. It sees a bit of growth, but almost no financial support.

Long ago I decided to write for me. To change topics if I'm no longer interested in my "niche" and let anyone who was no longer interested move along to find whatever they are interested in now.

The rest of the advice in the post is excellent. Follow it.
