It is a Monero client with Monero relays, so it's fair to assume a fair portion of the activity would be centric around Monero, and other similar topics.
This is only one example of what's possible.
quotingNostr does not need to be perfect, Nostr needs to be more curatable.

Clients + Relays + Self-Hosted Servers + Self Hostable Algorithms = Nostr Curation
Right now there is no easy method for users to create a proper Algorithm, sure primal has an "algorithm" of most trending notes but outside of that the other algorithm method you have is following people but that is pure 1 to 1 of every note they post, and sometimes unfortunately you might not share every exact interest as them, so it's not quite the ideal solution per se.
Curating will grow nostr faster than anything especially if we fine tune client, and Relays to be more synonymous, as in you go to woke client . io you start off with woke relays content, or if you go to big daddy Trump Client .io you get Trump maga deep throat relays content.
