Following on from yesterday's post on the CMU/Microsoft research, there are two networks in the research: the buddy network and the communications network for that month.
The buddy network has 240 million nodes with 9.1 billion edges. Which equates to 75 contacts per node/person (9,100,000,000 x 2 / 240,000,000). This is an indicator of the size of an individual's weak-tie / acquaintance network.
The communications network has 180 million nodes with 1.3 billion edges. Which equates to 14 contacts per node / person (1,300,000,000 x 2 / 180,000,000). This is an indicator of an individual's strong-tie / tribal network.
How do these results link to the second and third of Dave Snowden's magic numbers?
