An interesting article today in NY Times that tracked down a 60-year-old lady by following her search trail in the database of searches mis-released by AOL. "Her searches are a catalog of intentions, curiosity, anxieties and quotidian questions. There was the day in May, for example, when she typed in 'termites,' then 'tea for good health' then 'mature living,' all within a few hours."
Catalog of intentions. A gold mine for planners.
[Update] Aug.9 2006: I guess now the famous cartoon needs to be amended: On the Internet, nobody knows you are a dog until AOL releases your search history.
