Just ready a story relating to Yahoo on All Things Digital today and noticed they do a really nice job of explaining their use of tracking cookies:
Some of the advertisers and Web analytics firms used on this site may place “tracking cookies” on your computer. We are telling you about them right upfront, and we want you to know how to get rid of these tracking cookies if you like.
I’m impressed with the visual treatment and the fact that they’re very upfront with this information. Of course you’ll only see this message once (or whenever you clear all your browser cookies), but it’s a big improvement over most sites.
For more details on tracking cookies, see the EFF’s coverage of online behavioral tracking.
