Could it be group psychology? I'd like to chat with a psychologist or sociologist about this. My pet theory is that these sites, internal looking, closed etc all work on the basis of the group. And even "the wider open internet" also works on the basis of the group. However, a more forward thinking humanity may want to increase the group, the range , the diversity, or they may want to be more realistic about our psychologies....
