When I signed up for Curious Cat, a social media platform that lets you ask and answer anonymous questions, one of the first questions I got was why I signed up at all. I mean this literally: On the platform, someone asked me this. It's a fair question. And it raises a larger one: What do we hope to get out of social media at all? For many of us, the simple answer is we want to be known. I often think of the country song "Unknown," by Chely Wright.
