Definitely in the “to watch” category… Google Resists U.S. Subpoena of Search Data.

The U.S. Department of Justice filed a motion in federal court seeking a court order that would compel search engine company Google, Inc. to turn over “a multi-stage random sample of one million URL’s” from Google’s database, and a computer file with “the text of each search string entered onto Google’s search engine over a one-week period (absent any information identifying the person who entered such query.” (From Gonzales v. Google, Inc.)
