In Yours vs. Mine Dustin Curtis explains his preference to use “Your stuff” as opposed to “My stuff” in interfaces. It might sound trivial, but whether we use “My” or “Your” reveals something about how we view technology:

After thinking about this stuff for a very long time, I’ve settled pretty firmly in the camp of thinking that interfaces should mimic social creatures, that they should have personalities, and that I should be communicating with the interface rather than the interface being an extension of myself. Tools have almost always been physical objects that are manipulated tactually. Interfaces are much more abstract, and much more intelligent; they far more closely resemble social interactions than physical tools.

The answer for me, then, is that you’re having a conversation with the interface. It’s “Your stuff.”

This echoes Yahoo!’s recommendations:

Labeling stuff with “Your” instead reinforces the conversational dialogue. It is how another human being might address you when talking about your stuff. Even with MySpace¹, people say things like “I saw what you put on your MySpace.”
