I’m just adding local nip50 search support to damus clients, but this looks like a toy when compared to primals advanced search which you can’t really do on the protocol at the moment. So when i launch it people are going to be like “lame, we already had this on primal”. So unless I do something proprietary or spend the next 6 months trying to get advanced search into the protocol, then proprietary clients will always win.

My only conclusion is that clients will start competing with each other using off-spec advanced features, which means that you won’t be able to build a pure client anymore. Then nostr fails.
