A Threshold Reached...

Interesting little story of how "network theory" (via social media) underlied the solution to a 13-year-old mystery photograph from the 9/11 tragedy:


a blurb:

"...when information moves through a social network, it doesn’t move at random: The information pings from one 'node,' or person, to another, and the relationships between all those thousands of nodes create an intricate geography of influence and power"....
"...there’s a reason the photo went viral this year, when it didn’t go viral all the long years before. For the first time, it hit what information scientists call the epidemic threshold — the point at which a thing reaches enough nodes in the network that it can’t easily die out."
