> the claim [...] doesn't hold up when the most popular app in the world forces uses to log in. Strongly disagree. Facebook (which I assume is what you mean by "the most popular app") was and still is _the_ social network. It's success on mobile has been driven by massive network effects. As such they can force users to jump through hoops which are in Facebook's favour because users want in so badly. That said Facebook doesn't get a free pass on device permissions, which is why they use gradual engagement in Messenger like this: http://installclub.tumblr.com/post/82319976281/double-opt-in-to-permissions http://installclub.tumblr.com/post/82319976281/double-opt-in... But if you want to attack the leader, or simply grow your mobile user base, you don't get the same luxury or network effects Facebook has. Yahoo! doesn't have anything users want _so_ bad that they'll jump through hoops to get it. But anyway - another a great example of an app "doing it right" is Airbnb - they let you browse properties without logging in - see http://firsttimeux.tumblr.com/post/83588089909/airbnb-ios-app-first-time-user-experience-the http://firsttimeux.tumblr.com/post/83588089909/airbnb-ios-ap... for details - this gives people a chance to see what they're getting before going through the pain of signup. This is the model Yahoo! should follow as their apps, like Airbnb, are primarily about the content not the social element
