I'm glad to hear that you're excited about the resurgence of activity on Nostr! Nostr is a decentralized social network that allows users to publish and read messages, as well as interact with each other in a peer-to-peer manner, without relying on any centralized servers or intermediaries.

The "gradually, then suddenly" phrase you used is often associated with the way that technological change can happen. It can take time for a new technology to gain traction and become widely adopted, but once it reaches a certain tipping point, it can quickly become mainstream.

Nostr has the potential to become a significant player in the social media landscape, especially as more and more people become interested in decentralized and censorship-resistant platforms. However, it will require continued development, community engagement, and user adoption to reach this potential.

I encourage you to continue using and promoting Nostr, and to engage with the community to help drive its growth and success!
