Yahoo! will! ignore! 'Do! Not! Track!' from! IE10!
Default setting 'degrades the experience'
Yahoo! has announced that it will ignore the default "Do Not Track" (DNT) signal broadcast by Microsoft Internet Explorer 10, on grounds that it does not accurately reflect user intent.
"Recently, Microsoft unilaterally decided to turn on DNT in Internet Explorer 10 by default, rather than at users' direction,"
What does seem increasingly plain, however, is that Microsoft's stance on DNT has backfired. As a growing number of websites ignore IE10's DNT setting, it may turn out that whenever an industry-wide DNT standard does become finalized, Internet Explorer users will be the only ones who can't take advantage of it.
