Half right
It would be fine if user ratings only applied to your own searches. in other words you log into a Wiki or perhaps a Google user account, and your search ratings were saved for your own use.
Obviously there are some pretty huge flaws with this if Google or Wiki don't stand by pretty strict privacy standards.
The feasibility of creating such a system has already been proven, you can ask a few people in Chinese prisons all about Google and Yahoo's ability to store search results.
