Now Reuters reports Google CEO Eric Schmidt, speaking to press during the company-sponsored Zeitgeist 2010 conference, described plans to "take Google's core products and add a social component."
With a few social tweaks, Google's core product, search, would allow friends to provide friend more "tailored recommendations. Search quality can get better," Schmidt said. Doing so would take a few pointers from Yahoo, which recently added social components to its search engine.
