AOL released data on the 20 million searches 650,000 searchers did over a 3 month period earlier this year. The data contains a goldmine of information at 20 million keywords. This data, while seasonal and limited only to AOL data, potentially links data to specific AOL users. In the case of Thelma Arnold, a 62-year old widow who lives in Lilburn, GA, a NY Times reporter used the search information to follow the trail leading to her. This presented privacy issues leading AOL to pull the search information made publicly earlier.
