I've been following Matt since he first posted on here as Googleguy. I'm going to agree that since they went public, what Matt can and cannot say is very limited since it now has to be filtered through lawyers as all public comments for any public company.
That said, I'm sure he is still head of spam, but he also has other duties, like getting webmasters to turn in other webmaster for spamming. Makes his job much easier.
I've got a few sites that seem to of been caught in this latest wacky flux but I'm not doing a reinclusion request nor am I changing anything. The sites have done nothing wrong.
Seems like every summer we have wacky serps that settle out torwards the end of summer.
