At this stage of the game I really don’t care what you believe or others. I will say it again this is not a regular PR update. Jagger is running along side 24/7. PR will fluctuate for the next four months. Jagger will be removing pages and putting them back on a regular basis or just plain removing them. Serps will drop so will your traffic, this is google’s way of ridding itself of webspam.
If you lack a full understanding of Jagger I would suggest reading up on it.
But hey what would I know about such things? Have fun and good luck. I would elaborate but unfortunatley nobody would understand me.
The mirroring effect is standard for this update.
