It’s like football fans but music fans. Stans are derived from the Eminem song Stan. Super fans. Arianators, Swifties, little monsters, bey hive, and all the other fan groups. Pop crave and pop base are the news accounts for these fans. Like espn. They run a big part of Twitter imo. I also personally think they would be a great addition to nostr, as they would bring a niche that I have only seen on Twitter.
