I honor it on my websites as best I can, and am in the process of even rolling my own analytics to avoid using any third-party. Long story short, there's no way to enforce DNT from an end user perspective. From a web developer perspective, even if you roll everything yourself, its difficult to actually track down everything that you could be accidentally sharing. For example are you using a CDN? Does your host track this data, and share it? Do you use a third part API somewhere in a library you decided to use? So on, and so forth.
