Google is making a mess of things right now and quality of the results is definately going down. I just compared Google results to Bing results. Bing is a lot better at this moment (for the keywords I monitor): more relevant results and less spam. The scary part (for Google)is that Bing results are a lot better than a couple of weeks ago. Declining Google quality and improving Bing quality is something people at the Googleplex should start worrying about!
