Nice blog by the way :)

As an example I deleted the link to your affiliate site as whilst there might be good information, I am not a good judge of that – you are promoting medical advice so knowing where that medical advice is coming from is important, and the comment & link came from a umass.edu IP address whereas the owner of the site as far as I know is no longer a student.

I have to trust the links that get left on my blog for them to remain.

What if they ever cooperate with government agencies in any capacity, or if the government decides Google should somehow share their data for ‘national security’ or ‘public good’ reasons?

Google has a perfect right to operate as a company, however I would like to see these other companies(Bing, Yahoo, MSN) rise to a more competitive level vis a vis Google so we don’t encourage a total monopoly.

Here is what is stated specifically in the privacy policy.

Finally, if you’re interested in knowing what else we log when you use Google Public DNS, here is the full list of items that are included in our permanent logs:

* Request domain name, e.g. http://www.google.com
* Request type, e.g. A (which stands for IPv4 record), AAAA (IPv6 record), NX, TXT, etc.
* Transport protocol on which the request arrived, i.e. TCP or UDP
* Client’s AS (autonomous system or ISP), e.g. AS15169
* User’s geolocation information: i.e. geocode, region ID, city ID, and metro code
* Response code sent, e.g. SUCCESS, SERVFAIL, NXDOMAIN, etc.
* Whether the request hit our frontend cache
* Whether the request hit a cache elsewhere in the system (but not in the frontend)
* Absolute arrival time in seconds
* Total time taken to process the request end-to-end, in seconds
* Name of the Google machine that processed this request, e.g. machine101
* Google target IP to which this request was addressed, e.g. one of our anycast IP addresses (no relation to the user’s IP)

Google’s primary business is search and monetization of search results

Nowhere in the privacy statement does it categorically state that the data will never be used in other parts of Google’s business, and for readers of this blog they would be most concerned about search results, and not personal privacy.
Data in aggregate has value.

The data in many ways is very similar to toolbar data – as far as I know the webspam team is the only one that states they don’t use Toolbar data

Probably most useful if switched in big chunks – it costs money for an ISP to run DNS, but at the same time they make money from their data and giving Google the data fro free might not be smart.

For chunks of code for the lazy there is “header & footer” though it could just as easily be done with functions.php – I tend to be lazy
