If you are using mac, try reeder(http://reederapp.com/mac/). It syncs with a lot of online rss readers (I use feedly and instapaper). But where it shines is its UX. It does what you need without any fluff and does it elegantly. All essential parts are there without showing million buttons. Keyboard shortcuts also work perfectly. It is the only app that I didn't feel any need to change settings after the first time.
I think we will be able run them together in the future.
