I had a similar problem and created nooshub.com some years ago, it groups similar articles and uses the group size to detect news trends, but everything can also be configured per feed collection if you prefer chronological feeds. I use this to quickly check what is going on with high rate feeds, for other feeds like podcasts I keep it classic... You can see it in action on some pages that do not require login like https://www.nooshub.com/pages/7-news-international
