Don't Kill Google Reader
Kill products that are copycat of others (cough! cough! Google+). Whatever the efforts that went into recent changes of Google reader (Unified theme, Removing “Share” feature and add “+1” features) are the reasons why there was a decline in usage.
There are reasons why people don’t use Facebook as their newsfeed and Google plus is not going to solve it. I have shared a lot of articles until you pulled the “share” feature from Google reader to integrate with plus.google.com.
Above all de Führer too is not happy with your decision.
