I was attracted by the basic looking design, but I can't work out how to do anything. Why am I subscribed to a huge number of random feeds? How do I get rid of them? How do I view the content of the feed instead of opening a new window on the original site?
I like the predictive aspect Personally, I'm looking for something with a GR atom API, possibly to even run the existing GR frontend against, not a new UI with a different focus (I would prefer one focusing on curation and workflow over social or sharing).
