I'm part of a handful of different large user communities.... and the key is exactly what the user above stated. No one is posting publicly. Why should we? Google gave us a way to post with only the people we want to. That is why this is a great technology. Share the information with those we want to. None of these so called studies will ever be able to track the usage of the service due to that.
