Google has recently launched a very useful web service called Google Dashboard. It allows you to manage all your active google products like gmail, web search history, google analytics, calender, contacts, alerts, google docs, picassa albums, youtube videos watched and many more with a simple dashboard. It allows you to manage, edit and create your settings for the google services you are using. You have to click on the particular product to take you to the specific products settings page.
This is what Google has to say about Google Dashboard
We created the Dashboard to help you answer the question: ‘What information does Google have about me?’ Organized by product, the page displays product-specific data that’s associated with your Google Account.
Here is a video that describes dashboard.
Overall a nice service started by google that lets you manage google services while saving time.
