I think people decided that Social Network must be equivalent to "People I know, who know me," and Facebook is great for that. If you want to add in "people I used to work with," then LinkedIn is fine, too.

The reasons why most people SAY they don't use Google+ is because it's not the same thing as Facebook. I think they're wrong to have even thought of it that way.
