Google made a very socially awkward move with its rollout of Google Buzz last year. It was Google's attempt to build a social network in part by stringing together various existing pieces of its infrastructure -- your contacts from over here, your Gmail account over there, Google Reader if you use it, so on. The problem with Buzz was that while it was shuffling around this complex network of acquaintances from different parts of your life, certain wires had a way of getting crossed.
