Yes. User generated lists (NIP51) have lots of potential. Problem with NIP51 (at least for now & correct me if I’m mistaken) :
- no standard for indicating what any list should be used for… as new use cases (NIP) possibilities for user generated lists emerge how will clients know which lists to incorporate for each use case?
- little client support for user generated list for lack of use cases (see above)
- the content of these lists has to be curated by hand (for lack of client support) which means not many people will use them or keep them up to date.
