Hi Mae, welcome to Nostr! I would suggest playing around with different apps. Many of them have a different feed and discovery algorithms. Some, like https://coracle.social, even let you build your own algorithm if you are into that.

The app I work on, https://nos.social, has been running a program this summer to promote creators and journalists posting outside the usual topics. If you download Nos you can find a list of these folks by tapping on the Discover tab.
