In reply to brinked, this prompts me to mention something I've observed.
One of my sites that was hit by Panda 2 I decided to change radically as it was what you would definitely call a thin affiliate site. I thickened it up by adding more pages with original content. After 10 days this had no effect, so I decided to change the way it looked too. This involved changes to the CSS and then a couple of days later, some code changes and a different logo graphic.
After that, when looking at the search results and viewing the preview thumbnail, I saw that Google had immediately indexed the code changes and the new logo, but NOT the CSS changes from two days before. Today, three days later, it still has not downloaded the new CSS style sheet.
If CSS has become important in Panda's algorithm, this might be why making changes to a site doesn't seem to bring any better results for a while. Does anyone know how long, or at what intervals, Google fetches style sheets?
