Why would you discount someone who has been measuring relevancy of search results and only accept information from a group of people who don't use the system? You are making the mistake of identifying the wrong group as experts.
You may have implemented something that impressed you but when you move that solution into real use were other's as impressed?
That's what is probably happening with the google search team. A lot of impressive demos, pats on the back, metrics being met but it falls apart in production.
Most people don't think Google's search is good. Most people on Google's team probably think it's better than ever. Those are two different groups.
Spam filtering may have had upgrades but it is not really better for it and in many cases worse.
