Altough it's very practical for calculating networks LinkedIn style when all follow lists are public, it also keeps the social graph of users out in the open.
Not that it have to matter, but it can matter. It certainly is a privacy concern to some degree.
I think we ought to consider integrating private follower lists into our nostr clients. Maybe one would like to keep real life friends on a private contact list, rather than exposing all that data to datamining and similar uses.
If people remember the OxfordAnalytica scandal that facebook got their hands in. That's something that's doable on nostr without even having to ask nostr-hq for premision.
Maybe the more people use nostr, the more it would be a good thing if we had tools concealed the social graph as much as people would like to do so. Today, that's hardly an option on most clients.
