My experience as a user in nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg is at least 2x better Auto correct, faster loading notes, more content etc User growth data is interesting as well

Active 30 and 90 day interactions on the protocol… is this possible?

Things have definitely improved a LOT over the last year. It's impossible though to reliably measure users of a decentralized protocol by design. There might be some useful proxies, like published profiles / notes on well-known relays, app installations, etc: https://stats.nostr.band/

It has been growing quite significantly. Primal and Damus have improved a lot!
