On the “My content” vs. “Your content” language conventions front, a few resources—one, two—though, in the end, I’m leaning towards this approach as per Microsoft User Experience Interaction Guidelines:
“Use the second person (you, your) to tell users what to do.” So use second person for error messages, help, window or page labels, on-page documentation, and other places where the app is telling the user about the user’s content. “Use the first person (I, me, my) to let users tell the program what to do.” So use first person for buttons, menu items, and other controls where the user commands the app.
