One other thing about this statement:
In 2010, we launched two major algorithmic changes focused on low-quality sites.
I am pretty sure that in one of the google webmaster videos on youtube, he sort of "downplayed" the MayDay update, didn't he? I thought it was more considered a tweak than a "major algorithmic change."
Hmmm... any coincidence between having a new CEO at google and today's blog post on google's determination to battle spam?
