comScore US search, Sept 2011: Google still winning.

comScore's September US search engine report is out, and Google took back some of what it lost previously. In the long run though, it's fairly clear that Google hasn't really budged a whole lot over the past year.  Except for a temporary dip last Summer (2010), Google's US market share in search has been relatively stable, despite Microsoft's big bucks spent promoting its Bing search engine (end of May, 2009).
