In social networks, group boundaries promote the spread of ideas, study finds
But when group boundaries are eliminated entirely, people have almost nothing in common with their neighbors and therefore very little influence over one another, making it impossible to spread complex ideas.

@sjudd Ah thanks. An aspect of that statement that feels self-contradictory. Suspect it's somewhere in definition of boundary & in common.
@sjudd For me, ties to "birds of a feather" tendency, people group w/ similar others; notion "hey we're humans too" doesn't seem enough.
@sjudd If that notion of we're all humans were as compelling as the other boundaries we create then would we have everything in common?
@JerryBuchko I think commonality emerges from our shared differences.
