I don't know why you've been downvoted, when you make a good point. I do think that for young people, "the people who is around" will not be necessarily people near in the physical world. Teenagers mainly communicate through chat groups, and work trends don't seem to go towards encouraging more physical presence. Thus a reaction against current social networks would take the form of using more private, ephemeral channels (think Snapchat), and reduced, more controlled usage of public-facing ones (Tweeter, Facebook, Instagram).
