Hello and welcome to nostr, lol it isn’t like other platforms, you are interacting at the protocol layer here so you can switch between different platforms on nostr and all your relevant data follows you between each. When you get used to one platform like Damus or Primal, switch to something else for a while like nostrudel or Nostur, play around with the streaming platforms, or the longform apps. Either way, just have fun with it.
