…thus making Do Not Track (DNT) request header in fact useless. Entire point of DNT is exactly that it is informed choice of user, and noway a default setting that most users do not know of at all.

Consequently, DNT will stop perform a function of informing website about intent of user, and web developers will almost certainly stop taking DNT into account.

Unlike IE10, in Firefox browser, DNT is disabled by default, which is right solution.
