Quote:
The movie depicts the real-time evolution of the local friendship network of CouchSurfers in San Francisco, from January 2003. One "slice" represents one month. There are two slices per second.
Blue ties represent friendships from outside the organization. Red ties represent friendships formed within the CouchSurfing organization. We have no information about grey ties.
The width of tie is proportional with the indicated strength of the friendship: i.e., from "acquaintance" to "best friend."
