I'm on to them. I think every month when the update starts they all bring sack lunches to the office, eat their sandwiches at their computers, and have a good time watching everyone trying to figure out what they're doing. Then, after the update the Googlers all have a meeting to figure out what they can pull next time to get everyone going.
Take notice. Every month or so there's something new and mysterious they come up with.
Straight from the horse's mouth, the truth has now been told. Now we know for sure!
