What is the best alternative to Google Reader?
If browser based, I am switching to Feedly. It will import your Google Reader account automatically. Google will help you find a suitable replacement.
EDIT; I have now settled on InoReader, far classier than Feedly, (actually has a working Chromium extension with unread count!) Also can subscribe to feeds via RSS Subscription Extension (by Google). Double lovely, indeed, super nice!
It's being overloaded with traffic, but look at Newsblur. The code is open and on Github, the site is designed in a freemium model.
