I do occasionally, though usually Firefox' "awesomebar" will get me there anyway so there is not often a need.

My girlfriend does make extensive use of it for all sorts of things.

I think my mom uses it as well. My brother and dad I'm not sure about. Not sure what that says for a confidence interval, but many people still do. Then again, I'm sure there must be clusters of people (when clustering by who knows who) that never learned it's there, or who choose not to use it.
