If anyone around here doesn't already know about it, Google must want it to be very out-of-the-way. I would love to see typical users' reactions to this killer feature: it would be perfect for one of those hidden-camera, person-off-the-street, "No way!" sort of ads. I turned it off circa 2006 and I'm glad to see that it's still off.
