TDYR 193 - The Directory Problem: The Challenge for Wire, Talko and All Other Skype-Killers by DanYork published on 2014-12-10T03:55:01Z To me the "directory problem" is the greatest challenge facing new communications apps such as Wire, Talko and many more.... how do you build up the directory of users so that the app is useful to people? People will only use a communications app IF the people they want to talk with are using the app!
