I am by no means an impartial observer here; obviously I believe in the viability of the sovereign writer. I would also like to believe that Stratechery is an example of how this model can make for a better world: I went the independent publishing route because I had no other choice (believe me, I tried).
At the same time, I suspect we have only begun to appreciate how destructive this new reality will be for many media organizations. Sovereign writers, particularly those focused on analysis and opinion, depend on journalists actually reporting the news. This second unbundling, though, will divert more and more revenue to the former at the expense of the latter. Maybe one day Substack, if it succeeds, might be the steward of a Substack Journalism program that offers a way for opinion writers and analysts to support those that undergird their work.
What is important to understand, though, is that Substack is not in control of this process. The sovereign writer is another product of the Internet, and Substack will succeed to the extent it serves their interests, and be discarded if it does not.
Substack is at the center of media controversy, most of which misses the point that sovereign writers — not Substack — are in control.
