I noticed something about this update. Basically it is that older sites are targeted. Why because there are sites that slowly drifted back in the SERPS that simply changed their domain extension from .net and did a redirect all pages to .org or vice-versa .com etc. and ranked much higher. Exact same content no changes at all for years.
This is actually a tactic that has worked with every major GOOgle update including this one. However, be prepared for a decline immediately after doing this but the site will eventually rank higher than the previous one. By saying this I am probably goosing it, but whatever. Again you need to weigh the time that the site takes to come back versus lost profits etc.
Another observation is if your site had any quality problems that were flagged by GOOgle, they essentially turned up the penalty dial. Meaning your site got screwed more. This update really fells exactly like the April 2011 update, same organization, same rankings. Also subdomains "silos" were not affected even though other parts of sites, specifically pages with Adsense were hmm... Panda is achieving its objectives.
