What you are describing is, I think, one of many possibilities. I usually
(coming from the mobile community) describe this in terms of changing the
information set as the user changes location.

I think the imperative thing is to enable a more convenient user experience. By
enabling the system to draw conclusions about the user and his request for
information, we can avoid things like 2000 irrelevant hits in AltaVista, or
answering 500 questions to get personalized news. Since the scarce commodity we
are all competing for on the web is user attention, we have to make sure that he
gets what he wants (and gets satisfied), rather than gets something he did not
want (and gets frustrated and does not come back). Profiling the user and the
service, and using the semantic web on those profiles, will enable that.

Simplicity for the user is the name of the game.
