Glad somebody mentioned NewsBlur. I run NewsBlur and have been aggressive in developing it into a world-class feed reader. Native iOS and Android apps, a nice shared stories feature, and it's actively developed.

See for yourself, since it's open-source: http://github.com/samuelclay.

And because I run my own feed fetchers, you don't have to worry about the inevitable sunsetting and neglect of Reader. Also means I can do far more interesting things to feeds and stories that other Google Reader API-based clients can't.
