Nostr is under-promoted, which is why so many people are still unfamiliar with it. I think big content creators on mainstream platforms (Twitter, YouTube, IG, TikTok, etc.) stay there because of their massive following and wider reach. Their followers, for the most part, probably don't even know Nostr exists. Followers should be constantly reminded to try Nostr—just like YouTubers always remind their audience to subscribe, like, and share, or how Bitcoiners always say, 'Stay calm and stack sats.' Just keep promoting Nostr. Of course, creators must also be consistent in posting content there so their followers' efforts aren't wasted. People will leave if they see a social media platform is empty, has no followers, and lacks interaction.
