If I were you, I would attempt to create an MVP as a free newsletter. You can test the idea out and try to gain an audience that way. If you start getting subscribers, you can always use your free newsletter to promote a paid newsletter or website.
I tend to agree with the others that someone would pay money for someone with actual experience versus paying for curated content. But you could create a paid Discord where you have experts as mods or part of your team.
How would you monitize any of these ideas?
