Tedster, could you elaborate on your technique for removing the 90% of the content? I'm in a similar boat, I'm an ecommerce (comparison shopping) affiliate in a very specific niche. Our search results pages are indexed which creates a lot of keyword rich urls. This used to be a great thing but I highly suspect this is a key indicator for Panda. I am thinking of coming up with a list of the top 500-1000 or so Category-level keywords based on what urls Google used to love and still loves and for all others just adding a meta noindex. The search results pages on our site are pretty much the main part of our site so I can't do a 404 / 410. Does this seem like a good plan? Any insights would be welcome.
