All these social media sites ask all kinds of information; where you went to school, where you work, where you grew up and where you live now, etc. I understand that for places like FB (which is the only social media site *I* use), they ask you those questions so you can "connect" with other people that went to your school, where you work, where you grew up or where you live now BUT at least FB gives you the option to leave that blank.
Maybe I'm just a paranoid person, but I don't want every Tom, Dick and Harry to know everything about me or how to contact me. So why can't these other sites give you the option to keep some aspects of your life private, IF YOU SO CHOOSE TO! and not force you to share every little thing. Isn't there a happy medium somewhere?
