The Google Reader shut down is imminent, and RSS app developers are scrambling to move their apps away from the Google sync service. Some third-party apps have selected Feedly or Feedbin to drive their syncing, while others have decided to go it alone with their own syncing solution. Still others have decided to become a standalone reader with no syncing until they have time to evaluate which syncing service is the best for their customers.
