Creating Personalized In-Nostr-Newsletters from their favorites follow list would look something like this image (I took Lyn's last four notes/replies and plugged it into duckduckgo's ai: https://duckduckgo.com/?q=test&t=fpas&ia=chat and asked it to summarize all her notes into one neat summarized paragraph)

This would be great for food newsletters as well as any topic you want to follow, not only follows, but create a whole pull from nostr of what you want
