Facebook says we can forget about the personal space that six degrees of separation provides. On today's Facebook-inspired Friends Day, the social media giant says we're almost twice as close as we'd thought.
Facebook's data team writes that it crunched the Friend graph and determined we actually have only slightly more than three and-a-half degrees of separation. In other words, each of the 1.59 billion people active on Facebook is connected to every other person by an average of three and-a-half other people.
