Developer Spotlight: Kobo
By Bryant Lee - Yesterday at 2:00pm
Kobo is an eReading device and mobile app where people can read, discover and share over 2.5 million books, newspapers and magazines.
What Kobo Does Well
Kobo uses single sign on to simplify the registration process, avoiding the need for people to create new usernames and passwords.
Kobo educates people on the benefits of logging in with Facebook and shows screens shots of the sharing experience.
Kobo defined Open Graph actions for some of the most conversational aspects of reading a book – such as beginning and finishing a book – to encourage sharing and stimulate discussions with friends.
Kobo provides detailed controls for people to manage what stories are shared to Facebook.

Time Spent Reading
