I disagree. A large part of public schooling relates to love/belonging and esteem. Go $mascots! Science fairs, glee club, language clubs. Learning to organize support for causes. Learning to drive (there's a big social network!). And, indirectly, the zillion school newspapers and (I imagine), school websites.

We've been doing those things for a few generations now, but they haven't led to public newspapers. I don't know why we would expect them to lead to public electronic social networks.
