"Yours", or "Mine"

Great writeup by Dustin Curtis on whether the interface should refer to the user as “your” or “my” when talking about the user's stuff :

…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.
