I really thought this was already a well-established and known fact. I saw friend suggestions quite often after attending events where I ran into very loose acquaintances I never spoke to but share a few friends with. That by itself isn't too surprising, but the fact that this happens after we were geographically close led me to believe that this is common knowledge.
