An update to my earlier post about Michael Fagan's Google Ultimate Interface:  Michael wrote to point out that his interface does, in fact, support "Linux only" searches.  I just didn't look closely.

From an interaction design standpoint, I think Google does a good job of exposing complex functionality without overwhelming new users.  But they are sometimes guilty of hiding their light under a bushel (so to speak).  Mr. Fagan's search interface makes sure that light shines for everyone to see.
