It was difficult for me to learn this lesson personally. When I understood it, I deleted my Facebook account (best decision, btw), but I assume that even though my account was deleted there are still references to it all over. IDs in log lines, references not cleaned up -- enough to paint something of a picture of who I was and what I did with the site.
Now I'm more judicious in what I share, how I share it, which applications I give permissions. But I'm still leaking metadata everywhere. It's frustrating and terrifying that the cost of participating in our society is either a HUGE cognitive load in keeping an eye on all the data you emit or accepting that basically everyone will have full access to your (meta)data over time.
