Is anyone building this yet? 
90% of internet users only read and never post.

 Good idea. Oddbean might already be close to this 

 Is it already running? What is it good for? 

 Don't all clients basically do this if you just enter an npub instead of an nsec? 

 Kind off, but in this case there are no bookmarks etc either. 
Lurkers want to organize and remember their content as well.  

 disparaging someone for simply being private, isn’t a good look. 🤦🏻‍♂️  

 Your client leaks a lot of this info to relays when hitting them up, including your IP.

It also would mean when you use NOSTR to log into other apps, such as ecash, it would be missing that info.

Still I think it would be a popular feature.

How to create private follower list or private bookmarks? 

 Most clients already support this. Enter npub rather than nsec. 

It doesn't have to be **your** npub, it can be anybody's. Lurk as anyone you want and see what they see.

 We call them "the expendables". 

 Couldn't you do the same by setting up a profile and setting your relays to only use a local relay like Citrine? 

 I’m sure there are ways. This is what happens when you out the cart before the horse.

 Is there a specification for private follow lists, or another solution towards the same goal? 

 Yes, it's simply an encrypted blob that contains the followers.
