In my experience, the best way to ask about unpopular (here, on Lemmy) stuff is to make a post in a generic community. Discoverability sucks here and not many people are on here too so niche communities are often deserted.

So, if you make a post on popular lemmies like this one, you have better chances to receive a helpful response. I’m not sure how the situation with writing communities is, maybe they are active enough to be of use for you!
