Google has taken its search engine results to a new social level with the launch of a new feature that will allow signed-up users to recommend content and even ads.
Google faced privacy criticisms last year when it launched Buzz, a social networking messaging product that automatically revealed people's personal contact lists to the public.Matt Cutts said that Google hoped to address any potential privacy concerns with the +1 service by making it clear that any +1 tags are public.
To use the new recommendation system, users must create a Google Profile page. Any +1 clicks that a person makes will be publicly visible to their network of contacts, which is based on existing contacts in Google products such as the company's Gmail email and its instant messaging service.
