In recent years all major browsers have added support for the HTTP Do Not Track (DNT) header. The user is able to configure their browser to send the header with all HTTP requests to a web server, indicating that they do not wish to be tracked while browsing the site (see Wikipedia for history).
There are two contentious points with DNT:
There is no agreement on a browser's default DNT setting (should a browser request to not be tracked by default, or not?)
Sites are under no obligation to stop tracking when they receive a DNT request.
The problems for the user, naturally, are that they have to configure the DNT setting for each browser they use. But, more importantly, they do not know if it actually has any impact on the sites that they visit.
So, my question: If your site honours the DNT requests of browsers, should you inform users of this fact? And if so, how?
