I think there might be RSS readers with a view like this, but I don't use RSS readers, I use social media sites. (And on that note, it's still weird to me that Mastodon/ActivityPub sites don't let me follow RSS feeds. ActivityPub is just Better RSS, right? So I should be able to follow RSS feeds, boost RSS posts into the feed, etc. I know that doesn't work, we could make it work. We could figure it out.)
