I love RSS but I also believe there's not enough innovation in the space. Feels like most developers are burnt by Facebook and don't ever want to do anything other than providing you with a chronological feed of all feeds.
And then you subscribe to too many feeds, get information overload and miss content because you just "Mark all as read" when you're tired. Or skim through the headlines too fast.
I'd like an algorithm to process those for me. But specifically the sources I need. And there's nothing like that on the market.
Organize the entries by their importance so I could skim the top when I'm busy. Bundle the posts on the same topic. Create digest for high-frequency repetitive content. Combine RSS feeds, Twitter lists, and email newsletters in a single heap of organized content.
