For Twitter you can choose to get a notification for all posts by a specific user who you want to see all of their tweets. It’s useful I you want to get notifications for public service announcements, like fire or storm alerts. Or I guess if you want to really know when somebody who doesn’t post often posts.

This would be a useful feature to have in nostr, and we’ve got lists, so I’m curious if any apps have been using a specific list id for this?
