I was going to read it, but that pop-up asking me to sign in or sign up for your newsletter kept blocking my view. For a blog, with what I'd imagine would be limited readership, why would you insist that people login or sign up for your newsletter? I think you'll drive away more readers than retain using this method.

That is just a default behavior of Substack. It's not something I chose to set up myself.
