The Three AM Web Search

I just checked my google web history trends, and discovered the only hour of the day I haven't made a search since they invented this thing -- and I, idiot that I am, have tracked the web history as long as I can -- is 3 AM. I note this includes searches done in different time zones, so 3 AM may simply be a boundary condition for my consciousness. I wonder if Hillary Clinton is ready to google at 3 AM...?
