Lifestage, a new video app by Facebook, connects high school students with others from their school. Rather than profile photos, the app uses a series of selfies where users can show off their "faces." Users record videos to show off what they like and dislike and who their friends, pets, boyfriends and girlfriends are. People over the age of 21 will not be able to see the content. A quick swipe blocks and reports people but it is too soon to tell how effective it will be at punishing bullies and trolls. The app was just released last week and is certainly something to have on your parent radar, especially since it marks Facebook’s attempt to lure in younger users.
