I think after being here for a few waves of adoption , you realize a lasting adoption won't work like that. Not even had a wave of adoption for ages and ages.

Bitchat with the geohash groups built on nostr might be a promising one. Not sure nostr has ever had a nostr client that isn't a microblogging client have people join it. Potentially people using bitchat wouldn't even know it's nostr or what nostr is.

But there is certainly no likelihood of nostr-as-microblogging getting and retaining any waves of adoption in the near future.
