Over the last few months my bounce rate has increased massively, almost doubled. Seems to be caused by long tail giving me inappropriate traffic. All my user metrics have worsened since the Panda updates.
Ding, Ding, Ding! It's a death spiral, tell that to Google. They don't care because Panda is working for them and they don't want to take any chances, just in case they break it.
