why is there always a massive, massive traffic spike for a couple of days before Google does one of these Pandalizations where they rip all your traffic away?
I don't think that phenomenon is tied to Panda - we definitely see the pattern when there has been no re-run of Panda. Google makes a lot of updates and algo changes that have nothing to do with Panda at all. Panda may have run five times this year or so, but other changes are now in the hundreds, and some of them have been quite major.
