In regards to big vs small sites being affected.
I have one big and one small site, both cover the exact same topic but have different but same-topics content.
The big site got hit by Panda II. The small site was untouched.
Elsewhere there is a thread about "content reading level" and Panda. I wrote all of this content myself, so it's all written to the same level.
So maybe the big site was evaluated and the smaller wasn't.
(However, if really both sites were evaluated by Panda, the only salient difference between the two was ad to content ratio. The hit site used a fixed-width format and had two above-the-fold ads.
The site not hit had a floating-width format and only a sky-scraper above the fold.)
