I use damus mostly, but primal is a great tool for discovering new people to follow. Searching for people you don't follow often comes up empty on most clients, although it's improving. Early on you'll find "posts and replies" most engaging than the main feed. Check out some hashtags as well. Some of the more active ones that aren't bitcoin or nostr specific are #grownostr #running #foodstr and #coffeechain. Happy to help if you have other questions.
