@chrismak @mekkaokereke I hear you on the worry about "but they're spending *so many hours* on social media!" Then I think back to my own high school years, and remember that I'd routinely spend so many hours on the phone (landline) with friends, my ear would routinely be hurting afterward from having the earpiece pressed up against it.
I think "HUGE amounts of time spent building social links" is probably a natural part of teen-hood.
