@petehall, I think Panda is much deeper than similar content. I fixed that problem around January and still have no recovery (actually, it has gotten worse and worse). I'm starting to believe it has more to do with site structure, user engagement, and things of that nature. Perhaps similar content has something to do with the user experience aspect, but I don't believe for one second that it is the main cause of many people's problems.
