The media isn't the message.
A friend of mine who uses Facebook strictly as a way to connect with his friends recently posted a brief rant on his wall about people he barely knew in the real world sending him friend requests. He thought they were fake and had a few a harsh words for them. My friend is just a normal guy, with a normal day job doing normal stuff. He isn't a social media guru or anything like that. Computers aren't even the main focus of his work.
