@Scott, I'm very interested in hearing your results! Been a lot of people doing similar things. I witnessed a site go from badly mangled by panda to recovery back to their pre-panda levels with the conversion to a new domain name... design etc.
@Tedster, I thought the same thing about the constant referral to "medical terms" and "medical trust signals"... my skeptical mind considered it a PR move... ie. less people will listen to the importance/impact of the change if we talk about hobbies... if we talk about "will you trust medical advice..." and we (Google) are saying we providing a "better" SERP as a result of the changes... then we "google" look more important to humanity.
@Donna - I like your theory, how does that relate to a site like mine that has thousands of indexed pages... and post panda (after losing 70% of our traffic) we still have some fairly decent key terms ranking in the number 1 position? Wouldn't the site be stripped of all top of the SERP rankings if it is in the yellow/red zone?
