> In the US, all of these people get swept under the rug of "friends" in the FB era, and it's in this way that they are less granular if "friend" can mean just about anybody you've ever come across.
"FaceBook friend" maps roughly to "Anyone I have had some form of contact with and either don't actively hate, who says things I'm interested in hearing, or who I haven't gotten around to deleting". It's a completely distinct concept from "friend", in my mind. A FaceBook friend could be more accurately be described as a "contact", the way that I usually see it used.
I know some people who are deep in the FB Kool-Aid, or who label all acquaintances as "friends", but that doesn't accurately describe most of the people around me.
