US Representative Joe Barton sent Google a letter with 24 questions relating to privacy -- along with a week to answer them. I was annoyed that some seemed basic and already answered in a way that one of his interns could easily uncover. But Google's now replied to the letter with a 19-page response with answers. You'll find the responses in this PDF file. It's the weekend, so I'm off and leaving a deeper analysis until Monday. Google is providing the PDF file to media outlets that asked for it. I think we're the first to have done so.
