Something that helped me find non-bitcoin content is to:

1. Follow a hashtag of one of your interests

2. Follow npubs that appear in that hashtag result, if their content matches. Some people just spam a bunch of hashtags, regarless of their content.

3. Go to the profile of one of the npubs from step 2, and look at who they are following. Some of them will have names that make it obvious that they have the same interests in step 1. You can also look at their notes to determine if they're worth following.

4. Repeat step 3 with the new npubs you found in step 3.

Do this enough times, and you'll be following all 12 users of Nostr. 😜
