I see...  

nostr.band is not actionable...  just a picture.  

At least nostr.watch has an API, but there's no users/events count apparently. 

I don't see those resources to be really useful unfortunately. 

Any knowledge of some actual source of data?  

 You haven't even zapped me.
Google it. 

 eden.nostr.land is one i subscribe to as well... yeah it's massive, nearly at the top of the list

note that relay.damus.io is constantly being wiped
