Please remember that this "search engine" is still their core business, the rest is build around it and most of that is depending on people using the google search engine. Right now the search results are lame, after 2 tries getting crap users will move to other search engines to get better results. Since they are now on the stock market they should be carefull. That is maybe also the reason why nobody from google is mentioning anything about this.. I dont agree that they shouldnt care because they allready made billions, google has stock holders to take care of now .
