Tried gazillions of them, NewsBlur is the best (unless you need some fancy pants features like tiles or whatever).

Killer feature for me is the ability to group your feeds then making them availale via separate rss channels.

The mobile client is also pretty damn good.

Newsblur did add (somewhat recently) a "tiles" like view for graphic/image blogs to the web version. Newsblur might not always be the fastest at picking up hip new features, but I find that Samuel is pretty reliable about eventually adding the "greatest hits" of what everybody else has been doing.

It's also open source for those that want to try to directly contribute code fixes/ideas, but I've rarely felt that need. I'm happy enough just paying the Premium subscription every year and knowing that suggestions on the forums (used to be UserVoice, now is Discourse) get responses pretty quick.

I'd really like a way to "shuffle" stories, such that if, say, CNN pushes out 10 stories and the Guardian pushes out 10 stories 15m later, that the order of presentation shuffles the two of them instead of just showing one source.

Also, link deduplication, because sometimes articles from the e.g. the CNN Politics RSS overlap with the CNN US RSS
