nostr's main strength is its decentralized & open protocol, but to thrive, it needs:

smoother onboarding (i.e. easier key management and client setup for normies, without sacrificing security).

better spam and moderation tools like client-side filters (not central authorities).

enhanced privacy e.g. built-in options for anonymous posting and end-to-end encryption beyond dms.

relay improvements that are more reliable, scalable relays to reduce fragmentation and "spray and pray" issues.

content diversity that attracts non-bitcoin communities to break the echo chamber.

dns alternatives that push for ip-based or tor-integrated relays to cut dns dependency.

and maybe discovery features such as smarter algorithms for finding people and topics, like follow packs but more evolved than its current status.

overall, i see it evolving fast. there is great dev interest but focusing on ux and scalability will accelerate adoption.
