RSS is a great tool. I've been using it for more than a decade.
Just to remember that you can also follow SN content using RSS.
You can get the homepage posts on: https://stacker.news/rss You can get individual territories posts on: https://stacker.news/~<name>/rss
Suggestion time: perhaps a feed for the post's comments and feed to follow a given user activity would also be nice/useful.
