The author believes that personal curation of ads is an essential part of his relationship with his readers. He believes in his own value as a voice for products that he finds useful or interesting to his readers. It is very difficult to productize the trust of a specialist community, because smart people value authenticity and despise shills. If the author were to productize his model, which isn't impossible, it would require a great deal of effort to not lose trust, and his relationships with his customers would have to look a lot like his relationships with his sponsors (tightly coupled, personalized, most control left up to the consumer).
