How do teens really use Instagram, Snapchat and other apps?

Kara Swisher and Lauren Goode talk with The Verge's Casey Newton and Kara's oldest son, Louie Swisher, about how teens are using (or not using) apps like Instagram, Snapchat, Musically and more. Louie says he uses Snapchat because he needs to talk to people, and Instagram because he enjoys it, but avoids Facebook as much as he can because "there's no real point." He and Newton also review Snapchat's new Snap Map feature and Newton explains why the app's practice of deleting messages by default is so important. Later in the show, they answer your questions about Houseparty, Snapchat streaks and "finstas" — private friend-only Instagram accounts.
