I'm asking the same question, it's indeed a great question right now. If Panda has an issue with a section of your site it does indeed smack the entire site, at least it did to my 7 year old established site last update.
I do see an increase in traffic on a pair of smaller sites however that's most likely due to my competition having been cleared from in front of me so yes, it does seem Panda only hands out negatives or neutral at best.
My thought is that you had better check your site extras. By that I mean that if you have a comment section on a page you had better be getting comments, if you offer links to a social profile such as twitter or facebook you had better be getting tweets and likes. Got a feed? Better be getting an steadily increasing feed following.
Panda seems tied to social and, from what I am seeing, it could very well be tied to your inactive comment sections (etc) on a per page basis. It might be best to turn off all the gizmos that are not being used, at the very least you site speed will increase. I started by removing the Google search box, analytics and all of the adsense on Pandalized pages.
