Visiting my Feedly after a while made me realise how calm, nice and informative the long-form posting is compared to the raging rapid (mis)fire social media.

Newsletters, blog posts and Airchat give you context and explain. The antidote is not to shift the media but to change the medium.

Could Nostr appeal to the Substack writers and bloggers as their medium of choice?

You can receive zaps and bridging to RSS format for distribution should be easy if not already available.

Nostr clients can show rich media content and long-form.

As a first step, piping the current newsletter as notes (via RSS) can extend the readership and if you start to get zaps the attention follows. Shifting to Nostr notes first mode is not too far off even with the current tools.
