Facebook starts suggesting “People You May Know”

More and more Facebook users are seeing a new feature in recent days called “People You May Know.”

People You May Know is based on social proximity – Facebook looks at your friends-of-friends and suggests people that you have the most mutual friends with. So far, I’ve found several friends through the feature – it’s nice to glance at a new set of people every few minutes.

After last week’s launch of more robust privacy controls, “People You May Know” marks the second new feature in several days that employs the notion of friends-of-friends. Where else might FOF show up within Facebook sometime soon?

(I hear graph traversal is a pretty difficult technical problem, so don’t expect to see a “shortest path” feature a la the old days of Friendster any time soon 🙂 )
