I’ve really enjoyed 2020’s flowering of Substack writers, but I also enjoyed this criticism of the medium’s impact on thought: nintil.com/substack-milqu
One reframing: is there an adjacent model which can support book-depth thought? Or even three-month-essay-depth thought?

I don't think this is an incentives problem, I think this is the market correctly sorting for what people want. They don't want book-depth thought; they want it shorter & faster. The book-depth blog sellers have the wrong model - because there literally is no model besides books.

I think there’s a 2x2 here of thought and format. Many books are newsletter-depth long-form, but the most important books involve much deeper thought—years of accumulated insight. Substack promotes newsletter-depth short-form. Can one create a market for years-deep short-form?

Some short stories might qualify: there are Borges and Chiang stories which involve more insight than most books I’ve read. Not sure about the market side there.
