> Unlike some of Facebook's services/apps, Google does not automatically share your activity on some news feed every time you do something on their sites This is not really correct. In fact Facebook publishes only the activities "share" and "like". But not only that, Facebook gives me full control over who will see this. G+ is really dubious in this respect. Sometimes when I google search I see "xyx also goes to this page". Damn, so now I need to use Incognito every time I search for Christmas presents? Or what happens if I search for a different employer, will my work colleagues see that? Since one or two years Youtube is bugging me to be less pseudonymous. Yesterday they asked this weird question, at least this general bugging stopped. Sorry Google, if this is really only about Single-Sign-On, then keep a more clear separation of your services. Google+ sounds like a pretty heavy-weight Single-Sign-On solution, right? If this is your competition, you will lose your customers to competitors like Mozilla.
