Hi there. The question might be vague. I'm a developer who also became a content creator, and I write about UI/UX. Published a few books. Run Twitter and newsletter. Now, I can see that there are a lot of books and courses out there. Related to any topic. However, I want to create something that has much higher quality and at least at some degree unique. As an inspiration, I always refer to https://css-for-js.dev/, but I'm not sure. I know (more or less) how to grow audience. At least I'm confident here. I know that I can write good articles, use SEO, and all that. The question is: what for? Would an interactive custom-written platform that has all possible topics related to design (and even code snippets) be a good thing? People previously advised me to start small, and I did, and I got some results (revenue), but these are general books and there are a lot of other equivalents. Do you have any ideas in mind that might be "oh, if there was such a course I would definitely use it and share with others". Something premium, pricy, still WORTH it.
