Yup. This is what I see missing from all the non-parents or parents of kids under 10 on HN. Once middle school hits their whole friend/support system is probably on SnapChat and if you're not on there, you're instantly excluded from everything.
We actually have banned social media until 16, but fortunately iMessage was the defacto coordination and we accepted that.
No TikTok until adults, for a host of reasons.
