I know traffic fluctuates and user behaviour changes but... it's too obvious G has lots of influence over the earnings, more than the traffic becuase we all see patterns changing at the same date and almost the same hour. G is playing with their beta changes.
Other than that... I often think we, constant posters of the GAdsense branch should change our nicknames to: low, superlow, crazylowearnings, below-low, always-low, etc.
