I've worked on something like what you talked about, a "problems" discussion board, and indeed companies exist that offer such a service (i.e. https://canny.io/ https://canny.io/) but the issue was that in a forum explicitly about problems, users typically don't end up putting their money where their mouth is. Additionally, users aren't themselves designers or problem solvers and often spin their problem (or even proposed solution) in a way that they don't even really want or isn't effective from a business sense. All that is to say, I think that site you're proposing turns into "building product by democracy" which isn't super effective, actually. You're right about the specific situation of what I've built so far, it is a tiny version of those reports. But it's $10, and what I had in mind was not to necessarily target and solve those problems, but act as a starting point for entrepreneurial users to read and explore existing problems. From what I've seen so far, such a niche of entrepreneurial users might not exist - I think they probably do have their problem area already in mind, so unless I nail that area, they won't be paying for inspiration for random niches. My next steps might be to deploy some automation to make these documents, and therefore have something for any niche. But right now my engagement numbers don't seem to warrant that direction, unfortunately :(
