An enhancement for (Damus, likely other apps too) home feeds could be to limit either posts or posts and replies to where you are following both the reply parent author and reply pubkey.

Seeing all of someone’s replies is nice, but can become very noisy. I think twitter used to use the logic above, so you could see conversations without your following list, while also seeing non-rely posts.

I’m not sure however if this is a simple REQ to relays. Maybe a query engine limitation too.
