More On What Google (and Probably A Lot of Others) Know

From John Battelle’s Searchblog:

1) “Given a list of search terms, can Google produce a list of people who searched for that term, identified by IP address and/or Google cookie value?”

2) “Given an IP address or Google cookie value, can Google produce a list of the terms searched by the user of that IP address or cookie value?”

I put these to Google. To its credit, it rapidly replied that the answer in both cases is “yes.”
