Yeah some people have exciting contents in some particular niche/interest unfortunately it doesn't appeal. In my opinion, I can also attribute this to not having a solid Curation scheme in an area. For example look at the Chinese community, they have Curation schemes and accounts that focuses on Chinese contents.
We don't have such in the US or Nigeria. Some of the trailblazer in Nigeria on Hive have since left, and they didn't build any solid Curation scheme.
Curation will never be fair, and that's why I think communities should built it to some extent. It's such a complex issue
