Kobo today updated it's self-titled e-reader app for iOS devices to further extend its "social eReading" feature Reading Life, adding the ability for users to post quotes, notes, book covers and other aspects of their social reading to their Twitter feed. Readers can already use the Reading Life service to unlock achievements and discover new books, or post information about the book they are reading to Facebook. The company reports that Reading Life has helped its users dramatically increase their reading time since being implemented late last year.
