I suspect you've just solved your own problem.
The onus is on you the creator, to create. You've put in the proof of work & I'm guessing you'll be visible very soon!
Hash tags are the best we've got.
Discussion
Please go on writing a couple of more sentences to explain the hashtag thing. How could this guy for example have used hashtags? 🙏
Depending on the client, users can follow hash tags & will see these notes, even if they're not following the noter.
People tend to boost high value content from unknown plebs & nyms.
The problem for users is that they either get to see every note (global - high noise) or only the notes from npubs they're following. It's hard for a new npub to bridge that gap.
