Oh, I'm certainly not suggesting just giving in to it. But in contrast to the person I replied to, I think we should take teens' perspectives on their social cliques seriously, because even though the cliques don't have importance in society, they have impacts on those within, and our understanding of how cliques operate is surprisingly under-appreciated: https://en.wikipedia.org/wiki/Zachary's_karate_club

Now combine the natural fact of cliques and fissures in small groups with the amplification/reinforcement effects that social media provides, and you can see the potential for acceleration/intensification of social stresses during formative years - like Mean Girls but potentially spread across the entire internet, or at least similar cohorts.
