If you still read RSS, the best ever client is no longer Reeder 2 but an app by an indie developer. The app is called Unread. And it's built to help you read. No frills reading due to a very clean interface. But what impressed me most is the UI. It's all about swiping left and swiping right to move within the app. No menu tree to navigate. Very very cool.
Even sharing is as simple as swipe right and click share.
It's $4 though, but think of the caps you just bought. $4 is probably just the paypal fee that you paid.
If you wanna try out the state of the art and highly intuitive UI navigation, download his free App.net client called Riposte. Unread design is based off Riposte, so you get a feel of how it will be. It's seriously good.
