Does the Do Not Track setting in browsers actually do anything?
Google got a bit of grief for not having a DNT setting on it's browser, whereas Firefox and IE did, so Google is adding it. Not sure about Safari and the more obscure browsers. I use both Firefox and Chrome, and frankly I've never noticed much (and by "much" I mean "any") difference between them for ads and whatnot. Isn't the DNT thing voluntary on the part of advertisers anyway? Do any of them actually pay it any attention?
