Exactly. It's marginal benefit vs marginal harm. Teens can "communicate freely" over text, voice, and video calls, including sending each other photos... TO THEIR CONTACTS.

There is no need for location based recommendations, streaks, nudges, etc. They should be building their social networks in the real world. And if they need friends outside of school, that can come through parentally facilitated activities like sports, clubs, etc. Later you start playing Magic the Gathering at the nerd shop or go to "shows" at the VFW hall.
