I accidentally stumbled across Google’s Ad Preferences page, which lists all the “information” it has gathered about me through tracking cookies.

It was quite accurate with no false positives. I mean the following list describes me pretty much completely:

• Arts & Entertainment – Events & Listings – Concerts & Music Festivals
• Arts & Entertainment – Humor
• Arts & Entertainment – Music & Audio
• Arts & Entertainment – Music & Audio – Rock Music
• Arts & Entertainment – TV & Video – Online Video
• Autos & Vehicles
• Autos & Vehicles – Custom & Performance Vehicles
• Autos & Vehicles – Vehicle Brands – Porsche
• Computers & Electronics
• Computers & Electronics – Programming – Scripting Languages
• Computers & Electronics – Software – Internet Software
• Computers & Electronics – Software – Operating Systems – Windows OS
• Games – Computer & Video Games – Driving & Racing Games
• Internet & Telecom – Web Apps & Online Tools
• Online Communities – Blogging Resources & Services
• Online Communities – File Sharing & Hosting
• Online Communities – Photo & Video Sharing – Photo & Image Sharing
• Sports – Motor Sports
• Sports – Team Sports – Hockey
• Demographics – Gender – Male

I’m curious why it singled out Porsche, and I’m not sure about the very first Concerts and Events category either, but still, great job stalking my internet habits, Google!

I believe the following link should bring you to the page, but I’m not sure as I stripped a ton of session variables from the URL.
