Curious - all of our parents' preferred methods of communication cost money...letters, long distance phone calls, mobile phone calls. All of Josh's sister's (and her peer sets) methods of communication cost nothing (Instagram, Facebook, Kik, Twitter, Tumblr). Just an observation. Implications of this? Will companies one day pay us to talk to each other?!
Separately - isn't Skype basically Facetime over 3G/4G (and not just wi-fi)? What is Skype lacking here?
