Does anyone else have suggestions along this line?
Yes, I do. TV-Tropes is a brilliant source for discovering new works and artists, but unfortunately it is very US-centric (with a large subset of Japanese anime/manga), white, and so on. I have resolved to look up TVTropes entries for any works that I have recently read/watched/&c by or centering people from marginalized nations, or works by or centering racialized people, &c. If those entries exist, I add to them. If they do not exist, I make them. I also add their tropes to the main trope pages. This should increase their exposure. It has not been a very long time since I made this resolution, but here is one page, for the book Funny Boy,
that I made myself.
