After 5(6?) years on AdSense, I've come to the following unassailable, concrete conclusion late last year.
I'll call it The Only Law of AdSenseTM:
At any given time, space and condition, there are two types of publishers. Those having a good day, and those who aren't. To understand which is who is beyond human comprehension, and is ultimately determined by factors too complicated to, well, determined by publishers who are humans.
It has made me stop worrying and love the Bomb(s). :D
