Conversion troubles?

I released the latest edition of Definite Optimism today "Is Stable Diffusion really a big deal?" https://definiteoptimism.substack.com/p/is-stable-diffusion-really-a-big

It got quite a bit of interest on Hacker News, with 27 upvotes: https://news.ycombinator.com/item?id=32822598

What I am not very clear about is why so few converted, with only 4 conversions from 1926 views.

That doesn't seem very good, and I am not sure why exactly.

It also got a couple of downvotes on feedletter, which is always a bit of a shame.

Nevertheless, it was my highest upvoted post so far, and got the most traffic.

Just need to keep iterating.
