The state-of-the-art in feed readers was frozen in place sometime around 2010, if not before. By that time most of the format wars between RSS and Atom had long since died down and were all generally supported. The only new features to be added were simple functionalities like sharing out links from readers to social services like Facebook and Twitter. For fancier readers they also added the ability to share out to services like Evernote, OneNote, Pocket, Instapaper and other social silos or silo related services.
So the real question facing companies with stand alone traditional feed reader products–like Feedly, Digg Reader, The Old Reader, Inoreader, Reeder, NewsBlur, Netvibes, Tiny Tiny RSS, WordPress reader–and the cadre of others is:
- What features could/should we add?
- How can we improve?
- How can we gain new users?
- How can we increase our market share?
In short the primary question is:
What should a modern RSS feed reader be capable of doing?
