Substack blogging is very different from old-school blogging. The Substack culture puts much more emphasis on writing daily in order to maintain engagement, and to closely target those daily posts to a market that will open its wallets. And not necessarily because that market is being well informed but because it finds cultural validation in the writer's views. The result is that a lot of successful Substack bloggers are essentially repeating the same basic talking points again and again, never saying anything really new or substantial.

Ever talk to a YouTuber who started out hoping to share detailed info on the things they were personally passionate about, but then felt pressure to tailor their stuff to the algorithm and water it down in order to maintain any audience at all? Substack is the same economy.
