Intentionally but unbelievably, AOL has released some very sensitive data on their users, how they searched, personal information (usernames changes to numbers), all without their permission which is a big blow to AOL in their attempt to turn around their fledgling brand.

From a marketing perspective however, this information is a goldmine, a treasure trove of search data representing a specific user base (AOL users tend to be novice web users). Still, a lot of people are none too happy with AOL for releasing this data at the risk of identity theft of its users. Possibly an over reaction but poor form nontheless.
