if the algo and data are open source and optional that seems like a net good to me. are you concerned about devolving into existing social media problems? 

 my idea is more to notify me if someone I follow is a trending user, so that I don't follow him. 

 ha, what’s great about nostr is that someone could actually build such a thing. tho trending-ness won’t necessarily have such singular definition so there’s that too 

 It only "ends" with that if that becomes a central standard, which I do not believe will happen anytime soon on this protocol.
