Yes correct somehow. The fact that we use nostr do not imply that we need to have a WordPress account. The user can access the comment section of that specific website now, on any page/post.

it maybe could be a private group in Nostr? One private group for each link? Not sure... or maybe just a note thread in case. So the note will have as a main content the link to the article, and the user comment will be another note in response to that first note. If a new user respond, it will be responding to the note the first user wrote.

If a third user writes a new comment directly on the article/post it will generate again a main note with the link to the article + in response, the user comment. Make sense?

There's no need for the admin of the site to manage the comments, nor the spam.. Because no wp_table will be needed and the data will be in the relays the npub has already associated with.

Regarding updates, will be probably not the first feature to build, nor the "delete comment"... but for a First beta I think it will be great to have the possibility to comment freely... maybe zapping too :)

however, will be interestingto see how the current solutions in bolt.fun and nocomment are currently working + am not a dev so can not really guarantee 100% it's doable
