Facebook gives you lots of ways to keep up with your feed; you can rely on Push notifications from the Facebook app on your iPhone, Android or Windows
It appears to me, having searched FB help for “RSS” that they don’t truck in this no more, I can get emails and mayhaps the emails can be aggregated into feeds for my personal use?
