Chris, You may be jumping the gun just a touch here. The default setting for DNT is '0'. The implication is that if it is turned on that a user must have done it, and that's what you have to go with until you can get an exception. You've had that in front of you for over 2 years now. It's hardly the time to say that we didn't understand it - when it's the core design you've all been discussing for so long. Sure there are hacks - but for 95% of the population they wouldn't know how to pull those off. Secondly as I watch the DAA come up with their approach to http://news.cnet.com/8301-1023_3-57595191-93/do-not-track-opt-out-icon-comi ng-to-mobile-browsers/ I have to shake my head. Exactly how does the DAA expect to validate in 100% of the cases that the user clicked on the icon? I actually tried it on my desktop browser. First of all I had to enable 3rd party cookies and then it found 155 people tracking me which after I opted out resulted in a technical failure where it could not update the database. Result was consumer frustration and a distinct lack of trust with advertisers. Secondly they expect to release a mobile version next year. Great - exactly how do they expect to plug in to a mobile browser when no one else can. Secondly, if I set the app to send a DNT signal how will you know if I did it or I installed an app in front of the outgoing request to add a DNT signal. Rarely do I find myself agreeing with Rigo - but in this case I do. The only approach that is workable is a standard, otherwise there will be a fragmented marketplace with confusion and lack of trust. DNT is not going back in the box. It's shipped and with todays announcement by Pinterest http://bits.blogs.nytimes.com/2013/07/26/pinterest-allows-users-to-opt-out- of-being-tracked/ the content providers are climbing on board. Privacy is going to be a competitive differentiator going forward and everyone is now supporting DNT as a very simple Opt-Out mechanism. The UGE is critical as it will allow users to build a more trusted relationship with content providers based on access to their data. Currently there are probably half a billion browsers that support DNT and just Mozilla users send over 4 trillion signals a month (currently not being heard). I'd say it's a foregone conclusion that DNT is here to stay. Because as Aleecia says - you're not going to like the alternative which in itself will also require a technology solution. Right now the DAA's approach only has 2 million users and is basically still in alpha. It will be tough to gain much momentum when all the browser OEMs are already supporting a competing approach. But you never know.
