My mother is on Facebook, and she doesn't have many many Facebook friends other than me and the closest family. Resulting in Facebook posting an event to her Facebook news feed, whenever I do something on Facebook (because there's not much else to show in her news feed). If I post a comment in a discussion at Facebook, she gets to know about it, and sometimes joins the same discussion she too. Sometimes it's fun to hear what she thinks about the discussions I join. At the same time, feels as if Facebook is in this case a surveillance tool. I know there are other people I'm connected with, who I don't really know who they are and also don't have many other friends at Facebook. Those mostly-strangers-to-me are probably also being sent notifications about everything I do.
