Since the main Penguin Update thread has 700 posts and counting, I'm hoping to start a new thread solely focused on Penguin recovery tips. I have a site that was hit by Penguin and I am trying to work my way out of it.

I think reason I was penalized was my content. I was inadvertently keyword stuffing. This is just the way I have been writing content for years. I have updated the content on my main pages where I have fixed the blatant keyword stuffing. My density levels are much more in line. My main question is:

I have over 80 blog posts that have some instances of keyword stuffing. Do I need to go back and fix all of these pages? Some of the posts are over 3 years old? I also have some really old pages that are buried in my site that may have poor content. Should fixing these old pages be a priority?
