Hi Charles and welcome to nostr, but Nostr is more than social media, think parallel universe internet, primal is a social media app that runs on nostr just like Damus, Nostur, Amethyst, and more, but then there are blog apps, streaming apps, video hosting, messaging apps, and so much more… since you are communicating on the protocol level and not on just tue app, you take your followers, data, and your follows to every nostr app you use.
