No, it's more along the lines of ditching hierarchy for tagging and locality. I don't like the current
implementation, and I really want to see that as part of Nautilus, but the idea rocks IMO. I believe
this is one of the things that make people like GMail so much. This is how people think about
things.
Also, notice that find and locate, and tracker, will continue being nice ways of finding files, but
not for my mom =P.
