The Nostr is the only protocol I'm using now after dropping the centralized ones years ago, so you could say I'm a Nostr maximalist.
That said, if you come from centralized platforms with a good engagement record, I would sincerely advise you to keep using them and do not expect to simply switch over in an evening.
You will get a lot less engagement here and may become frustrated. Instead, just be patient, post consistently as a secondary platform, or maybe mirror all your posts elsewhere here.
I think the Nostr will eventually grow and give you lots more satisfaction, but it will take time and we don't want people to burn out!
