Youtube to hand over all user histories and IP addresses!
Due to a recent judge ruling, google will be forced to turn over every record of ever video watched by youtube users, including user's names, and IP addresses to viacom. (story)

Here's an excerpt of the most-dugg comment thread for 2008-07-03 :

I don't like it one bit.

"this is the first time since YouTube started that I've heard that it records EVERY video you watch."
Realistically, you should assume this to be the case without anyone telling you. EVERY large commercial website records EVERYTHING you do. Page views and user actions are stored in meticulous detail and analysed to see how people interact with the site, so as to improve layout, navigation, advertising, etc. Youtube will have literally terabytes of logs in their data warehouse recording not only every video you've watched, but how long you watched it for, which links you clicked on that page, which related videos you rated or commented on, and probably a hundred other little details that seem meaningless on their own but build up a sophisticated profile when considered together.
