Consumers Delete Cookies at Surprising Rate: “The report found 28 percent of Internet users are selectively rejecting third party cookies, such as those placed by online ad networks.” - I question the notion that 28 percent of Internet users have the software to do this, much less the know-how to go in and delete selected cookies by hand. Firefox (along with all the other Moz browsers) lets you selectively reject cookies, but it isn’t 28% of the market by any means. I suspect Jupiter’s survey model is seriously broken.

Update: I have been reminded that IE also lets you selectively reject cookies, if you’re willing to tolerate the interface for doing so. Bad web wonk, no cookie. Are 28% of internet users willing to tolerate the interface? I still doubt Jupiter’s numbers.
