So there we have it. The Google Lord giveth with one hand, and takes away with another...
So there's no Google Circles for the time being. Just a bit of labs research. Although people's reactions to it suggest that there is a genuine hunger for a new way of sharing with your personal information.
The misinformation was clearly leaked though, and they certainly were in no rush to dispel the rumours, which at least means that they can get some good buzz monitoring out of the situation.
So still a well done for Google. Can't wait to see what they have up their sleeves socially - maybe combining the good elements of Wave and Buzz?
