A short article in last week's New Scientist talks about a recent patent of a search algorithm incorporating user choice into the ranking system. As I understand it, a page receives a boost if it is clicked on from a particular set of search results, raising its ranking the next time that keyword is searched for. The idea is to reduce the impact of spam results, which might occupy top SERPs but receive fewer clicks if they contain obviously irrelevant results.
I've searched the archive and I think this is the patent they were talking about, although I'm not completely sure as I've lost the New Scientist article!

So would this kind of algorithm improve Google's results?
