To make things more transparent from Google’s point of view, it is providing a Dashboard to allow us to manage the data it collects.
Sadly all I found was just how easy it is to get yourself totally lost in its services. Don’t get me wrong; it did a nice job with the Dashboard. But the fact of the matter is there is really too much going to effectively manage any of it. This is especially true when you consider how many different Google services most of us are likely using these days at one level or another. Even if you do nothing but watch YouTube videos and use Google for searching, you have data out there.
I have found myself using Google Dashboard to help me keep track of the various services offered by Google. After all, it does not take too much to overwhelm most people with information overload. So to a degree, I guess Dashboard is helpful there.
