Unless a surge of people began looking up my site topic it has the feel of an update, has anyone else noticed any changes starting on the 29th?

YES. My Penguin-affected site is up 70% today (30th) compared to yesterday (29th). Sadly, even if that holds true through this evening, that would only represent a 5-10% recovery relative to what Penguin took away, but I'll take it.
