Google said, "We're the largest public DNS service in the world, handling an average of more than 70 billion requests a day."
So I guess webmasters had a reason to be wary. Those using Google Public DNS no longer have to use Chrome or Google Search or surf sites with AdSense or DoubleClick ads for Google to know what they are doing on the web.
Of course, they have their privacy polices.
In any event, A WebmasterWorld thread has one senior member making a sarcastic remark:
if goog is your DNS it doesn't matter if you using their SE or not.
ya know....cause they just wanna make the web better. *gag*
Do you use Google's Public DNS? I don't but I do use Chrome - so it doesn't matter.
