Im still of the opinion this is a shakedown of the new system and 'normality' will resume shortly. Google has said all along this is an infrastructure change, two incompatible systems with one replacing the other - not a major algo change. To do both at the same time seems a little suicidal (too much to go wrong) In doing so it is unlikely that they would import old data from one system to the other, they would send out the bots and essentially start again - large sites may be getting stored differently so a complete crawl of the site may have to completed, I cant remember the default page crawl rate but it is slow - around 10k pages per month, if they have been doing this for 6 months it still leaves a big shortfall in deep pages.
I cant wait for 6 months time when I can look back on my posts and see how wrong I was! Can I post Images? (Newbie!)
