Is there a write up somewhere on what you’re doing? Or are we still that early lol.

You can shove any .rss feed into https://atomstr.data.haus/ and it will spit back a npub to follow with the feed. With YouTube it's a bit more involved, since they don't advertise rss but tl;dr is you grab the channel ID and add it to this crafted url: https://www.youtube.com/feeds/videos.xml?channel_id=THE_CHANNEL_ID_HERE
Ah great, thank you
