OK, I'm 180 degrees from most of you. My site, www.EXAMPLE.com, saw traffic increase by 30% on 22 and 23 of September. My site also saw positioning on key terms sky-rocket to 1 & 2 positions for over 9 keywords from 3 - 6 positions previously.

On Aug 5, some key terms went from 6 & 7 positions to 3, 4 and 5.

I've seen some people reference activity on Aug 23 and Sept 6 as well.

It would seem to me that Google is doing bi-monthly updates. Now the real question is are they updating PR or tweaking their algo?

Perhaps both, maybe their twekaing algo's on the 22 - 24th of every month and changing PR's on the 5 - 7th.

I'm willing to take bets that their is another wave of volatility around the 6th of OCT.
