Go on search bar, type a hashtag of something that you have interest on, and follow people from there. You can also make certain hashtags show up on your feed, for example you could follow #monero and all posts containing that hashtag would show up on your feed. I know its not as good as Twitter, but we will get there with time. Don't give up on #Nostr, a lot of people like your content and don't want to use Twitter to see it, why not mirror everything to Nostr?
