Yesterday, Feedly announced that it was migrating away from Google OAuth to Google+ for authenticating users. After backlash from users, the decision was reversed. This is a great example of a company listening to user feedback.
Also noteworthy in the post is that Feedly is planning to offer alternate login options such as Twitter, Facebook, and WordPress in the coming weeks.
