Do you. What comes naturally. If you post only here how do you let people know about your posts?

Nostr should bring you joy, happiness and value by being useful. If it feels like work then you’re now doing something right.

You’re not using YouTube, Netflix etc. to market it to others. You may share some of their links/content because you find something valuable to share.

Play with nostr and find new ways to use it. When you discover something brilliant and it does not exist build it.

That’s how Twitter got hashtags, threads etc. People just invented them because they were useful. 

Do you, and just do it.
