Ben Thompson(the author of stratechery) is a smart guy, but his free articles, even though that they seem deep, do lack domain/technical knowledge. I've noticed that on the subjects of self-driving-cars, car-sharing and now on logistics/delivery/e-commerce - notice how abstract and detail free this article is.

But actually, that could be a great content authoring strategy: create a really good, smart name for yourself. write articles that the smart people of the internet like to read. give them the wrong answer, they will be forced to correct you. collect replies(including those from you your closed forum) and grab the right answer. publish and charge.

Don't know if that's the strategy. But it could work.
