I do understand that in order to create something popular you need to create something good but you also need to properly communicate what you do. And proper communication is as hard as creating something good. So, I do know you need to "find an audience", and that is why I've posted it in a few places.
Having said all that, reading these comments made me feel somewhat demoralized because the advice wasn't really actionable. As a noob in this space I went in expecting to get some advice along the lines of: "your idea is bad", "the website design needs to improve", "your app keeps crashing", "there is no way to make money from this", etc... But all I've got was this generic "find users" advice.
"Find users" isn't intrinsically bad advice, but the way it was delivered felt really bad. How do I find users? Should I post about it in some platform? Maybe I should write a blog post about it? Running ads is a viable approach? Given what I have, what communities should I try to engage?

But I don't want to create a business right now. I just want to create something that people find interesting. I already know how to build things for myself, now I want a different challenge. But right now I feel stuck because I've built something, nobody seems to care and I don't really know how to improve my situation.
