I believe nostr is doing more than fine.. these things take time and new users will only come when more infrastructure is added to suit their needs or when most of their network is already in. most people don't understand the need for nostr, they see it as just another platform and they see no benefit in it whatsoever, only those more involved care and understand the need and benefits it brings.
we haven't even met all the early adopters needs, to cater for the rest is still a bit far down the line..
