Google has added a new service for its Google Account holders that gives them an overview over all the Google services they have signed up for.

The idea behind this feature is, according to Google, to provide you with greater transparency and control over your own data.

The Dashboard gives Google users an overview over 20 products and services, including Gmail, Calendar, Docs, Web History, Orkut, YouTube, Picasa, Talk, Reader, Alerts, and Latitude.

We are not so sure that Google users will find this overview over what Google knows about them comforting, as this is quite a lot if you are an avid Google user.

We are not too concerned about this, however. We believe Google (GOOG) is doing everything in their power to keep this information under lock and key. One single newspaper story about Google leaking private information would undermine the public’s confidence in such a way that it could damage the reputation of the company forever. They won’t risk that.

(That being said, we would not be surprised if Google is providing such data to the US authorities, if this can be of help in cases of national security.)

The Google Dashboard does give you a good way of checking the status of your Google account, however, and it helps you find errors and inconsistencies in the various settings of these services.
