Apple seems to have no idea how to get people using a few of its apps. Messages (iMessage) and Facetime in particular. The stupid thing about these apps is that there is no "Buddy List" to know who else has it. I have no idea which of my friends have iMessage or Facetime, so how can I possibly use these apps? I go on Skype or Whatsapp or Viber, or others, and I know how has them and it's way more convenient. What are they thinking trying to make these apps without buddy lists?
