Let's try and sanitise our analysis: I think its easier to judge the value of this offering from Google on a site with high members other than Social Media junkies who are both fatigued by the existing offerings as well as sated. For argument's sake let's assume I have a charity website where there are several classes of stakeholders: volunteers, donors, service users and political lobbyists. They all convene on the website to read news and to donate etc. Now think how useful Google Friend Connect can be. Firstly, the stakeholders don't know each-other so Facebook and Twitter wouldn't help. I think we're the wrong group of people to analyse the wider proposition that Google is making.
