Oh sure, if you want to turn over even more control of your life to Google The Borg. //

From the Google DNS FAQ page:

Privacy

What information does Google log when I use the Google Public DNS service?

Google Public DNS complies with Google’s main privacy policy, which you can view at our Privacy Center. With Google Public DNS, we collect IP address (only temporarily) and ISP and location information (in permanent logs) for the purpose of making our service faster, better and more secure. Specifically, we use this data to conduct debugging, to analyze abuse phenomena and to improve our prefetching feature. After 24 hours, we erase any IP information. For more information, read the Google Public DNS privacy page.

Is any of the information collected stored with my Google account?

No.

Does Google share the information it collects from the Google Public DNS service with anyone else?

No.

Is information about my queries to Google Public DNS shared with other Google properties, such as Search, Gmail, ads networks, etc.?

No.
