You do great work and are a pillar.
If I were in your shoes, I’d look to standardize your format and delivery of content. Example:
9am - GM
10am - political
11am - movie trailer
etc
I’d use tags always to try to get new followers.
If I were a company making a Nostr app, I’d look for ways to partner with you. Content creators need to make money. Zaps might not be enough long-term
