Please explain what you mean "Google forces it down our throats" ?
It appears to me that anyone could exist and use most of Google's services without ever creating an account or logging into G+. Yet as a marketer it is the least expensive and most effective tool in the world. What I perceive as "force" in social marketing is Facebook's invasion of privacy practices that range from changing privacy parameters and telling members after the changes have been made, collecting and selling private data without telling members and participants of surveys or trying to market a "Job" app which ultimately makes a members give access to their personal page to potential employers. As a marketer I made a lot of money on Facebook, prior to quitting a year ago I had 3,400 "friends" and 70,000 "fans" and had done some effective ad campaigns. I quit because I simply got sick of watching member's being exploited, disrespected and Facebook not making any sincere attempt to change their M.O. From Day #1 Facebook was built to exploit people's private data... it will always remain that way. Google on the other hand has protected and respected my private data since the beta of GMail started. They provide the best mail service in the world while to the best of my knowledge have ever allowed anyone to see my correspondence... intentional or unintentionally. Google provides a great value without forcing it on anyone.
