The service will be optional for users and won't replace any of the traditional Google search options you're used to. What it will do is add another layer of results based on your social circle, which in turn could help deliver more relevant search results. For now, the functionality is still in experimental form, but users with Google accounts are able to sign up to use the service. Google also warns that early users may notice the button comes and goes as it makes improvements to the service.
