The average Facebook user has 245 friends. The average friend of a friend has 359. Each person’s friend list is loosely connected. There’s a mere 12% overlap when friends are matched against friends’ friends. Yet 80% of friend requests were reciprocated and fewer than 5% of Facebook users “unfriend” somebody.
From: The Psychology of Facebook. And originally from the PEW study we referenced last week. These are very cool tidbits of info about Facebook usage.
